We have been disturbed by recent statement on
this question by President Eisenhower and Mr. Dulles.
We hear from our High Commissioner in Canada that during
Dulles' visit last month he said to Mr, Pearson that he
was constantly stressing the distinction between tactical
atomic weapons and the hydrogen bomb, that United States
defence policy was now based on the use of small atomic
weapons, and that reliance on conventional weapons would
be hopelessly costly. Mr. Pearson was reported as saying
that Canadians were realising that Canada would inevitably
be involved in international trouble even where no
Canadian commitments were involved, and that this worried
Canadian public opinion and would lead to more agitation
for having a voice in important decisions.
Clearly this question is of the highest importance, and ministers here have recently considered it.
They Invited the Foreign Secretary to arrange for consultations to be held with the Canadian Government with a
view to the submission to them in due course of the draft
of a joint communication on this subject to the United
States Government, provided of course that the Canadian
Government wished to Join with the Government of the
United Kingdom in this manner.
