I don't think they should go. They've never supported the war, they're against it. And even though Noodles said that the troops didn't decide to start the war but Bush did, they're still fighting the war.
Those people are fighting for something, dying for something, and then some band comes along to play for them even though that band's against what they're fighting for.
It'd be a lot better to have a band play who actually support the war.
Blergh, that ^ doesn't sound as clear as it did in my head.
I see it similarly. It's a bit awkward. It's not black or white.
