From 1950 –1962 Canadian, British, and American intelligence assessed “The Likelihood of War” by weighing USSR policy, ideology, and strength. The Korean armistice, East German riots, changes in the Politburo, Sino-Soviet alignment, and a USSR H-bomb detonation impacted their threat analysis.

They are proudly displaying the American flag which was hand made by them during their long imprisonment at a Communist POW camp. Officer shown kneeling in front of the group is identified as Maj. David F. Macghee, 137 El Central St., Moorestown, N.J. Maj. Macghee, a B-29 pilot of the 371st Bomb Sqd., was captured on 10 November 1950 after his plane was shot down by flak and MIGs. His B-29 was the first B-29 to be shot down in the Korean conflict.

In 1969 Ottawa asked if Safeguard would destabilize the balance of power, fuel the arms race, undermine SALT, endanger Canadians, or reshape NORAD. Reports warned it might “hinder rather than help” arms control, eroding Canada’s credibility. #CanadaDeclassified #ColdWarHistory #SpecialInterest
