If you support the troops, you want the US to win. If you want the Iraqis to win, you must be hoping for a lot of American troops to be killed.
"Who do you want to win?"
Good. However, some protesters say they support the troops because they don't want them to be killed. How does one answer that?
Of course, some of these people will not accept any counter-argument. However, I would say that we have been fighting a two-week war, we've taken less than 100 casualties and nearly "conquered" a country the size of California. This is a great, largely bloodless operation. And "peace" demonstrators who express unhappiness about it are showing their hand: they DON'T care about the troops. They DON'T want the mission to succeed. They're unhappy because it's going well.
Answer: Bull Shit! If they didn't want the troops killed, they would not be out there demonestrating. All that accomplishes is giving aid and comfort the the enemy and encourages them to keep fighting or not to comply.
