i've never gotten it either.
i think it's to rouse patriotic vibes and keep all of the citizens slaves to the government. because, if more than just a few people disagree with something as powerful as war, something bad could happen, maybe even challenge government.
i think that i'm going to the nearby air force base, asking my dad who works there to find a few troops to come along, and find a public place with a sign visible that reads: support our troops. then i'm going to let the troops lean on me. it sounds fun huh?
yeah right, i'm just very bored.
but i agree, what a stupid phrase. i wish i knew who invented it so i could flog them with a small chicken.
