kill communists... kill socialists... kill, kill, kill...

Why was the cold war necessary?

Why did we kill three million Vietnamese people (at least two thirds of which were innocent civillians?)

Why did Saddam Hussein's socialist regime need to be "taken out"?

Here are some clues:

“Since trade ignores national boundaries and the manufacturer insists on having the world as a market, the flag of his nation must follow him, and the doors of the nations which are closed against him must be battered down. Concessions obtaind by financiers must be safeguarded by ministers of state, even if the sovereignty of unwilling nations be outraged in the process.” [from unpublished paper in 1907, quoted in William E. Diamond, The Economic Thought of Woodrow Wilson]

“Our industries have expanded to such a point that they will burst their jackets if they cannot find a free outlet to the markets of the world . . . . Our domestic markets no longer suffice. We need foreign markets.” [1912, quoted in William Appleman Williams, The Tragedy of American Diplomacy]
