I'd read an eloquent letter to the editor in the Washington Post the other day, by one George Kennan:
I am extremely concerned about the shameful, almost total passivity of Congress during the period of preparations for our military attack on Iraq. (I recognize as exceptions Sen. Robert C. Byrd's noble statement in the Senate and the belated but vigorous statements of Sen. Thomas A. Daschle.)
Congress's inaction is a dangerous precedent in executive-legislative relations. In light of this precedent, future presidents will be tempted to seize virtually dictatorial powers under the title of commander in chief, and nothing in our history rules out the possibility of their yielding to that temptation. This seems to be the meaning of the recent crisis.
...well, I must have forgotten some of my Political Science classes, because Keiran Healey points out why I should have recognized the name:
Kennan is, amongst other things, one of the twentieth century’s most important diplomats. He formulated the idea of “containment” which defined U.S. policy towards the U.S.S.R during the Cold War. I believe he is almost a hundred years old.
Here's an biographical sketch from a 1996 CNN interview:
George F. Kennan was the chief architect of the policy of containment and one of the most influential figures of the Cold War. Trained as a diplomat, Kennan began his career in Moscow in 1933. He served there off and on for the next three decades. In Moscow in 1946, he drafted his famous "Long Telegram," a document that sounded the alarm over Soviet expansionism and became a prescient warning about the coming Cold War.
