Barack Obama, 2002:

I don’t oppose all wars. My grandfather signed up for a war the day after Pearl Harbor was bombed, fought in Patton’s army. He fought in the name of a larger freedom, part of that arsenal of democracy that triumphed over evil.

After September 11, after witnessing the carnage and destruction, the dust and the tears, I supported this administration’s pledge to hunt down and root out those who would slaughter innocents in the name of intolerance, and I would willingly take up arms myself to prevent such tragedy from happening again.
