105. Memorandum From the President’s Deputy Assistant for National Security Affairs (Scowcroft) to President Nixon1


  • Message to Prime Minister Trudeau on Canadian Participation in the ICCS

The Canadian Government has been under considerable domestic pressure to withdraw from participation in the Vietnam International Commission of Control and Supervision (ICCS). We have learned that the Canadian cabinet will decide tomorrow on whether or not to withdraw from the ICCS.

The Canadians have been the prime movers in the ICCS, and their departure would be an extremely serious loss. We therefore strongly recommend that you urge Prime Minister Trudeau to continue Canadian participation in the ICCS.

Secretary Rogers has recommended that you call Prime Minister Trudeau and personally urge him to reach an affirmative decision.

We have also prepared a letter (Tab A) from you to the Prime Minister which we can transmit today should you decide not to call him.


That you telephone Prime Minister Trudeau today and urge him to continue Canadian participation in the ICCS. (Talking points are at Tab B.)

That you sign the letter to Prime Minister Trudeau at Tab A.

  1. Summary: Scowcroft recommended that Nixon call Trudeau to urge continued Canadian participation in the ICCS.
