I explained that it was recognized that the
2,
United States has responsibility under North Atlantic Treaty
arrangements for strategic air operations and that the
Canadian Government would not wish to hinder the fulfilment
of these responsibilities.
We could not agree, however, to
permit unrestricted use in peacetime of the facilities in
Canadian territory by giving approval for all such activities
in advance subject to Service notification.
Preparatory
arrangements which the Strategic Air Command might undertake
in Canada and which would not involve the use of fissionable
materials, such as training programmes, provision of storage
facilities and the deployment of aircraft, as well as the
movement; of non-nuclear components might be handled on a
Service-to-Service basis.
On the other hand, for any
activity which involved the movement, storage or use of
fissionable components or the nuclear core of atomic weapons,
it was our view that the Canadian Government should be consulted in each case at the highest political level, and that
the channel should be civil rather than military.
Arrangements would have to be made to permit such consultation to
take place at very short notice in the event of an emergency.
If the U.S. authorities-wished to proceed with negotiations
for a canopy agreement, it was our view that the terms of the
agreement should be placed squarely within the framework of
the North Atlantic Treaty.
I also drew Mr. Arnesonfs
attention to the agreement concerning the channels of
communication between the- United States and Canadian Governments on defence matters, which is set forth in Appendix No.
of the Journal of the P.J.B.D. for June 3rd and 4th, 1948.
Mr. Arneson made notes of the points which I hs
3a
made and said that he would first consult Mr. H. Freeman
Matthews, Deputy Under-Secretary of State, who./. is conversar
with this problem; he will also probably later consult Mr.
Acheson and officials of the Defence Department.
Mention
was made of the possibility of a meeting between Canadian and
United States representatives on a high level, including Mr.
Pearson and Mr. Acheson as well as representatives of the
Chiefs of Staff of both countries, as a prelude to any
agreement.

Mr. Arneson. fully recognized the risk of a mis4.
understanding arising between the United States9 Canada and
the United Kingdom as to the nature of the commitment which
has been given by President Truman for consultation in advanc

TOP SECRET

United States and the United Kingdom Government apparently
boil down to an agreement to have continuing consultations
on the circumstances which might give rise to the employment"
of the atomic weapon.
The United States has clearly
reserved the sole right to decide upon the use of the atomic
bomb, particularly in the event of an attack upon the United
States.

Some thought has been given to the possibility
9.
of defining more clearly the circumstances in which atomic.
Mr. Arne son said that he had tried
weapons might be used.
to work out some consistent criteria.
Apart from coming to
very general conclusions such as that atomic weapons should
be used only in the event of a general war, he had found it
impossible to establish any criteria which could be applicable to all cases.
Indeed, considering that the value of
the atomic bomb as a deterrent rests partly on the
uncertainties in any potential aggressor’s mind as to how,
when or whether it could be used, any definition of the
occasions for its employment would remove some of the
deterrent value.
Mr. Arneson's preliminary conclusion was
that it could be said almost with certainty that any attack
upon the United States or another NATO country would result
in retaliatory action by the United States with atomic
weapons.

10,
In concluding our conversation, Mr. Arneson
explained why the United States Government attaches prime
importance to the use of Goose Bay by the Strategic Air
Command.
It was possible, in the event of an emergency,
that nuclear components would not have been deployed to
Strategic Air Command bases in the United Kingdom or to
other.strategic locations along the periphery of the
probable targets.
If such deployment had not taken place,'
the United States Government would wish to use Goose Bay
as the base from which initial strikes- against the enemy
would take'place.
As the take-off of the heavy aircraft
employed consumes largo quantities of fuel, their fuel supply
would have to be replenished in the air by tanker aircraft.
A bomber laden with an atomic weapon would take off at
Goose Bay and refill its tanks over Harmon Field, or possibly
another field in Newfoundland, before proceeding on its
mission.
On completion of its mission it would seek to land
in the United Kingdom or at some base 'in the European
theatre.
In the event that nuclear components had been
deployed overseas in advance of the emergency. Goose Bay ■ *
would be regarded as an important staging area in the movement of aircraft of the Strategic Air Command to and from
more advanced bases.
' Do you think that it would be unreasonable for
11.
the Canadian Government to give prior consent in advance to
strikes with atomic weapons from Goose Bay or Harmon Field
in the event of a clearly-established Soviet air attack on

North American territory, subject to as. much prior notifica-

tion as might be possible in the circumstances?
It seems
to me that we could not reasonably refuse our agreement to
the use in such conditions of Canadian facilities or airspace, and that we would in fact be anxious to see a counteroffensive undertaken with the minimum of delay.
Furthermore,
we might find in such an event that wire communication
between Washington and Ottawa was severed and that it would
take some time to discover alternative means of communication.
If this concession were made,' it might be easier for the
United States Government to agree to our desire for political
consultation before the use of Canadian territory for the
delivery.of atomic weapons in circumstances not involving

I shall be sending you a further report as’
soon as Mr. Arneson informs us of the preliminary reaction
of the United States Government to your comments.
