Please be aware that the Olympics of 1976(Canada), 1980(Russia), and 1984(US) had significant boycotts by a number of countries. In the case of 1976, Canada's Olympics were boycotted by the African nations due to a New Zealand rugby tour violating another official boycott of South Africa! Boycotts are a tool of international relations, and certainly some would say a valid alternative to more violent alternatives.
