A Brief History of U.S. Interventions:
1945 to the Present

The engine of American foreign policy has been fueled not by a devotion to any kind of morality, but rather by the necessity to serve other imperatives, which can be summarized as follows:
* making the world safe for American corporations;
* enhancing the financial statements of defense contractors at home who have contributed generously to members of congress;
* preventing the rise of any society that might serve as a successful example of an alternative to the capitalist model;
* extending political and economic hegemony over as wide an area as possible, as befits a "great power."

This in the name of fighting a supposed moral crusade against what cold warriors convinced themselves, and the American people, was the existence of an evil International Communist Conspiracy, which in fact never existed, evil or not.

The United States carried out extremely serious interventions into more than 70 nations in this period.
