If the Benjamin Franklin quotes don't work...toss out new ones.
Here's a few:
--We make war that we may live in peace.
Aristotle
--The purpose of all war is peace.
Saint Augustine
--There is nothing so likely to produce peace as to be well prepared to meet the enemy.
G. Washington
--We win here or lose everywhere; if we win here, we improve the chances of winning everywhere.
Gen. MacArthur
--Never turn your back on a threatened danger and try to run away from it. If you do that, you will double the danger.
Churchill
--Once we have a war there is only one thing to do. It must be won. For defeat brings worse things than any that can ever happen in war.
Hemmingway
--War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself.
John Stewart Mill
--The second type you have at these protests seems to be the people who want to mislabel Hitler. Everybody in the world is Hitler. Bush is Hitler, Ashcroft is Hitler, Rumsfeld is Hitler. The only guy who isn't Hitler is the foreign guy with a mustache dropping people who disagree with him into the wood chipper. He's not Hitler.
