By way of Dan Wood’s email signature:

– Theodore Roosevelt

Also, he had a link to a speech given by Senator Byrd the day the war began. It’s entitled “The Arrogance of Power” which expresses, in very eloquant words, some thoughts that I agree with.

Update: A longer version of the Roosevelt quote above can be found at The Theodore Roosevelt Association site. The quote appeared in the Kansas City Star on May 7, 1918, during World War I.
