Here is the beginning of the Guardian article.
1.Good decision by Canada. This is not akin to the US boycott in 1980 but instead is a first step toward more countries doing the same, sort of a domino theory of the Olympics.
5.It would be interesting to look back to 1980 when President Carter took the US out of the Moscow Olympics and expected others to follow suit. Not many did. How did he manage this? Did he pressure the USOC directly or did he have some special legislated power to say that we were staying home?
Then earlier the Africans decided to boycott in 1976 when a New Zealand rugby team toured South Africa. Rugby was not even an Olympic sport. I thing Ethiopia, then in our pocket, stayed in the games but the Kenyans and Tanzanians boycotted along with a lot of other African nations. For that, Henry Rono never got a shot at an olympic medal. I can't remember if Kenya boycotted in 1980.
