Procedures for U.S,

-A.C. Flight Clearences

It will be recelled that rather over a year ago
discussions were held with the State Department extending
over a period of two or three months in an effort to draw up
a canopy agreement" between the two governments regulating
the u.se of facilities in Canede by the U.S. S. .C. and establishing procedures to be followed in connection with such
activities. The discussions eventually broke down when it
became apparent that there were certain requirements held by
each government to which the other could not agree. The U.S.
Government was at that time unwilling to enter into any
agreement which would appear to qualify the right and responsibility of the President of the United States to make the
decision that atomic weapons should be used. The Canadian
Government for its part could not agree to surrender the right
to decide whether or not Canadian facilities should be used
for atomic strikes in any particular situation.

It was obvious, however, th t some kind of procedure
2.
would have to be evolved to permit the U.bs .1. to carry out
those operations in Canada appropriate to its peacetime programme of preparation for an emergency. The proposal for a
canopy agreement having been abandoned, there was substituted
the "Agreed Minute" to which Mr. Pearson and Mr. Acheson gave
oral assent on June 14 last. This Agreed Minute was designed
to afford a record of procedures which had been developed on
an ad hoc basis for the mutual convenience of the two governments and which did not represent a formal intergovernmental
agreement. It provided for frequent consultations between
the Canadian /mbassedor and the Secretary of State or his
representatives, and expressed the hope "the t by such consultations it will be possible to arrive at common appraisals of
situations which may necessitate the use of stomic weapons".
It also specified the channel throu h which requests of the
U. . Government "for permission to make use of facilities in
Canadian territory for the deployment of atomic weepons...
and for the conduct of operations involving the use of such
weapons, or to overfly Canadian territory with such weapons"
should be directed. By implication, therefore, it indicated
the willingness of the U. • Government to obtain the prior
consent of the Canadian Government for U. . . .C. special
op ations in Canada, although it could hardly be regarded
as legally and formally binding the U. . Government to such a
course.

AS far as is known, the U. . authorities have

meticulously followed the procedures outlined in the Agreed
Minute since it was approved. Toward the enc of list summer,
it was realized that these procedures probably appeared unduly
hampering to the U.S.A.F. in the conduct of training end
si ilr operations of more or less routine significance. It
became known that the U.S. S.A.C. was somewhat impatient at
havin to follow a rather elaborate clearance procedure for
operations of minor importance, partly because of the measure
of delay inevitably involved, and perhaps more because of the
necessity of working through the State Department in each
esse. It was considered that there might be a distinction
made between the clearance procedures for routine and for
politically significant operations, and there was prepared a
tentative list of categories of operations on the basis of
which such a distinction might be made.
It was recognized that the effort to define par4.
ticular eategories of operations in this way ropresented a
reversion to the concept of a canopy agreement setting out
specific procedures to be followed in connection with defined
types of operations. This effort had formerly proved unsuceessful. The Agreed Minute, however, would presumably continue
to apply as a matter of general doctrine, and it micht readily
be modified in the inturests of convenience to permit less
cumbersome clearance procedures for categories of operations
of lesser significance. This approach would enable Governments
to agree on what would be essentially administrative procedures
where they had not been prepared to record formal agreement
in terms of general principles.

One difficulty was to establish the validity of
S.
the suggested criteria for distinguishing between routine and
politically significant operations. The R. J.A.F., lacking
direct experience of the type of operation carried out by the
U. . .
was not prepared to reach s decision as to
whether or not those criteria would prove workable in practice. It was decided to arrange for an examination by suitable
representatives of the R.C.A.l • and U.S.A. . of the technical
issues involved. Accordingly, at the meeting last Auguat of
the P.J.B.D., A/V/M Miller discussed these que tions briefly
with General walsh of the U.S. .7. While A/V/M Miler has not
circulated a written report of their talk, he informed the
Department of External Affairs informally on his roturn to
Ottawa that the proposed criteria appeared suitable.

Further developments were delayed temporarily by
6.
the Ottawa and Rome meetings of the North Atlantic Council.
Before anything further had been done in Ottawa, the Embassy
in Washington was informed by the State Department that
Mr. Lovett had written to Mr. Acheson a letter which put the
question in a somewhat different light. Mr. Lo ett apparently
wished to return to the old concept of a more or less formal
canopy agreement, with one significant difference. He was
now prepared to have such an agreement include a specific
provision to the effect "that initial strikes from Canadian
bases or overflying of Can dian territory on strike operations will not be undertaken without prior ap roval of the
Canadian Government through government-to-government channels".
He framed his proposals in terms of three categories of
operations, superficially resembling those prepared here;
indeed, it appeared that his letter was based primarily on
the discussions between A/V/M Miller and General Walsh. He
listed his three categories as follows:

"A. Intransit flights not involving strikes. Such intransit flights would include stops at bases in
Canadian territory and overflight of Canadian territory
on flights to Alaska, European areas or other bases
outside Canadian territory.
"B. Deployments to Canadian bases in preparation for a
strike.

"C. Actual strikes frora Canadian bases or involving
overflight of Canadian territory."

Ab indicated above, he was prepared to agree that
7.
the consent of the Canadian Government was required for operations in category C. It was his understanding that the Canadian
Government was prepared to grant a blanket prior authorization
tor the activities outlined in category 4, subject to "a
mutually satisfactory prior notification procedure...preferably
on a service-to-service level".
With regard to category B, he admitted that "the
Canadians have not specifically indicated a willingness to
grant a blanket prior authorization for deployment in preparation for a strike". He bent on to say that "it is believed
that this matter should be the subject of further conversations
at the political level with the Canadians with a view toward
acquiring such authorization, together with a mutually

The United ......

we have rot as yet met the request of the State
9.
Department for formal comments upon Mr. Lovett’s proposals.
Since we first learned of them, a number of the people concerned,
both on the Canadian and on the U.S. side, have been tied up
with other matters, lany of the implications of Mr. Lovett’s
su gestions, moreover, were by no means clear, and various
conversations have been held with a view to obtaining a more
exact understanding of what they would involve. It is now
known fairly accurately what Mr. Lovett wants, and it remains
to be decided whether or not the Government is prepared to
meet his wishes.
In the first place, he is anxious to obtain agree10.
ment on a procedure whereby the U.S.A.F. could carry out the
various routine operations involved in its general programme
of preparedness without in each case having to obtain the
consent of the Canadian Government. In this regard, he would
wish to have accepted the right of the U.S.A.F. to conduct
such operations merely upon a basis of prior notification
according to terms which may be agreed. He appears quite
prepared to keep Canadian authorities fully informed, both
through service channels and, if it should be desired, through
the diplomatic channel, of the general purposes and extent of
these preparatory programmes. Provided that satisfactory
procedures are established for keeping the Canadian Government
informed of what is going on, it is suggested that Mr. Lovett’s
wishes on this point can be met.
11.

He is prepared to accept what has always been con-

sidered the basic Canadian requirement, namely that the consent

ol the Canadian Government must be obtained before actual
strike operations are launched either from Canadian bases or

throueh Canadian air space. On this question again no

difficulty is seen in what he suggests.
12.

The critical problem, it would appear, is the ques-

- 5 =

of special weepons to intermediate or advanced bases (such as
bas s in the U.K., in Greenland, 1® Alsska, or in Canada) may
be no more than a matter of assuming and maintaining a position
of full preparedness. To this, the Government micht be willing
to agree, subject to the conditions sug ested above in paragraph 10. Deployment operations mey, however, be undertaken
in consequence of political or other developmonts likely to
lead to an early outbreak of hostilities. Operations of this
nature would be of immediete and critical significance to
Canada. It has been mede Quite ol ar thet the U.J. military
authorities, and Mr. Lovett, wish to have prior author! ition
for these activities as we 1. Mr. Lovett apparently considers
that such prior authorization by the Canadian Government would
be reesonable in view of the arrangements made for elose political liaison between the two governments, through which the
Canedian Government would, it is supposed, be kept fully
informed of the political developments and of the intentions
of the V. . Government.
It should be noted that Mr. Lovett’s category B.
refer* to "Deployments to Canadian bases". Deployment
operations, even of an emergency nature, through Canadian
airspace to other territory such no Alaska or Greenland, might
be regarded as felling within his category A., "Intransit
flights not involving strikes".

13.

The difficulty concerning deployment would arise
14.
only in a case where the appreciation of the two governments
might differ as to what action should be taken. Such a difference night easily occur in the event of a critical situation
developing in the Far East. It la unlikely that the Canadian
Government would wish fletly to refuse the use of Canadian
sirspece in preparation for strikes against Far Eastern
targets should the U.S. Government insist thet such preperation was urgently necessary. Nevertheless, there is no doubt
that it would be easier, in such a situation, for the Government to impress its views upon U.S. authorities if it had not
previously author! ed the use of either Canadian bases or
Canadian airspace for emergency deployment.
— further point raised in Mr. Lovett’s letter was
IS.
his wish to have the arrangements "bilateral in nature and
ex-NATO, leaving any authorisation for S.A.C. oprations under
the NATO agreement as completely separate end apert from
these errengementa". While this passage appears somewhat

unattractive, it has been explained to us in fairly satisfactory
terns by U. . officials. Tha NATO provisions for mutual
support are so ill-defined, end the po sibla complications
to which they might give rise so undesirable, that in the
interest of efficiency and clarity it was desired to supplement
(but net to supersede, the general NATO undertakin s by a
specific understanding between Canada and the U.S. in regard
to strategic sir operations. It may be mentioned that the
particular matters proposed for Inclusion in the agreement
concern Ga ac da more directly than any other NATO power except
the V. ., as the North American continent must of necessity
be the base of all NATO strategic air operetiona.

16.
It should, of course, be remembered that deploycent
through Canadian sirspace to Alaake would not necessarily be
en action taken to wet the needs of MATO.
17.

This papur has attempted to cet out the background

and significsnee of Nr. Lovett’ a propossl for a general agree-

ment to cover ' .
&amp;.4.C. operations in Canndn. It is
understood th t MT. Pesrson will discuss the matter with
U. . ministers and officials lx the neer future, end will
wish to express the views of the Government on the particular
isauss involved. There are suggested below certain points
which Mr. Pearson might make to the U.S. ministers concerned.
1.
The Canadian Government is anxious to cooperate in
every possible way in simplifying the procedures to be
followed by the 1. . .F., and wishes to ensure that the
letter's operetions shali in no way be impeded by unnecesssrily cumbersome arrangements. To this end it
welcomes Mr. Lovett’s pro possl to draw up a detailed
agreement specifying elearly
a) those eategories of operations for which it is
prepared to grant blanket prior suthorizstion subjeet
to the establishment of a mutually satisfsotory notiflection procedure.
b) those categories of operntions for which it
considers that its concent would heve to be sought
through the forml government-to-government channel in
the light of perticular circumstances.

The Government considers, however, that the categII.
ories of operations suggested b Mr. Lovett obscure to
some extent the distinction indicated in I. between
operations of routine importance and those of major
political significance. There is suggested below a
redefinition of the various categories of operations
which the Government would regard as more suitable.

Flights to bases in Csneda or involving overflight
(A)
of Canadian territory for purposes of training, testing
and related aspects of the general progremne of
preparedness being carried on by the U. . S.A.C.
Deployment of atomie weapons to bases in Canada or
(8)
Involving overflight of Canadian territory undertaken ns
a part of the general progremne of preparedness mentioned
in (A).
Deployment of atomic weapons to bases in Canada or
(C)
involving overflight of Canedian territory occasioned
by a specific political situation or development.

Actual strikes from bases in Canada or involving
(D)
overflight of Cansdian territory.

The Government 18 prepered to grant prior authority
XII.
for operations of the types indicated in (A) and (B)
above, subject to the receipt of suitable prior
notification as discussed in V. below.

The Government would wish to indicate its consent
IV.
before any initial operation of the types indicated in
(C) and (D) above are carried out. It should be added
that the Government has already undertaken to respond
with the utmost promptness to requests relating to
S.A.C. operations, and for some months has had in effect
arren ements designed to ensure that in an emergency its
views would e given to the 1. . Government within a
very few hours. In view of the arrangements already
made to provide for full and frank consultations at a
high political level concerning "situations which may
necessitate the use of atomic weapons", the U.S. Government should at any time be in a position to anticipate
with some confidence the decision of the Canadian
Government in a perticuler situation. It is to be
. . . 8

hoped that the consultations will become sufficiently
intimate to remove any likelihood of a situation arising
concerning which either Government is ignorant of the
other’s views and intentions. It will be appreciated
that the Canadian Government is unwilling to commit
itself in advance to permitting the initial stages (such
as emergency deployment) of operations which in the
event it night oppose.
V.
The Government wishes to be informed regarding the
nature and extent of the various progremmes of routine
operations indicated in categories () er d (By above. To
this end it would wish to be given in edvance, preferably
both from ... to C.A.8. and fron State Department to
Canadian Embassy, a general outline of proposed V. . . •.
operation s involving the use of Canadian facilities. Such
an outline might be made available on an annual or semiannual basis, and might be amended and supplemented from
time to time by more detailed information. In addition,
of course, in accordance with normal operations procedures,
there would be required prior notification on e service
to-servce level of details such as flight plans for
individual flights. These two forms of prior notification would satisfy the Government's requirements in
regerd to operations of the types indicated in categories
(1 and (B)
The Government has noted Mr. Lovett’s wish th at the
VI.
proposed agreement should be "bilateral in nature and
ex-N TO". The Government sees no objection to the 8uggestion that the proposed agreement should be specifically
bilateral, on the understanding that it wot id supplement
(rather then supersede) any undertakings set out in WTO
defence plena. It would prefer, however, to have the
preamble of the agreement make some reference to the
mutual obligetions of Canade and the I ,i e, as members
of HATO, to make such provision as may jointly be
deemed necessary for their common defence. Such a reference need not specify that the particular arrangements
set out in the agreement are s part of the approved N T0
defence programme, but should merely indicate that the
egreement is undertaken in fulfilment of the ceneral
NATO requirement regarding mutual cooperation in defence
planning and preparation.
