Would I ever fight in a war? Yes.
On one condition however: that the war in question be a CIVIL war, where the southern United States tries to separate from the north... again!
Now, I'm not sure if Obama would measure up to ol' Lincoln, but I would feel obligated to take up arms to keep the union whole. Why, you might ask? Because both Aqizzar and Janet will be among the southern ranks, and I'm sorry to say that the odds will be stacked against us Northerners considering that.
We'll need all the help we can get, and so, saying that, I'm preemptively conscripting Toony. Toonster, I know for a FACT that you're from Canada or Maine or Rhode Island or something, and thus are obligated to fight by my side in the American Civil War 2. Jakkarra, you might be British if I remember correctly, so take a catamaran, go across the Atlantic and head up the Mississippi. You probably won't survive the actual combat, but it might distract Aqizzar long enough to deal a decisive blow in a dramatic, slow-mo fashion; preferably with an American flag, just like Mel Gibson in "The Patriot". That was such a good movie.
Don't think it won't happen people, we have to be prepared for everything! No offense Janet/Aqizzar, but in situations like that, it's friend against friend and brother against brother, there's no room for cowardice. You understand.
I'd be raising the Battle Flag and heading to Richmond for my commission, myself. Not, mind you, because I have any ounce of loyalty to the sort of ass-backwards dystopia that "South will rise again!" rednecks imagine, wherein they've established Jesusland and purged the population of folks whose skin tone isn't on the light side of peach. But rather because I'm fiercely loyal to my home state of North Carolina. Actually, whichever side they landed on, I'd be on that side. Which is kinda how it worked for most folks in the South the first time around. They weren't fighting for whatever-the-hell-the-South-was-fighting-for, but rather just because they didn't want "them" coming around and taking their farm.
Fratricidal warfare aside, I'd serve in a general draft situation although I'd move like hell to get into OCS and get me an officer billet. If it weren't for a bum ticker, I'd already have served in uniform. My father was a 32-year career Naval officer, and my family has a long, long tradition of military service, going back to at least the Jacobite rebellion.
That said, I don't romanticize military service, but I don't fear or despise it either. It's an honorable profession, and in my experience, veteran soldiers are the *last* ones to want to go to war. My half-brother is on his 3rd tour in Iraq right now, and believe me...he's ready for peace. Especially since he'll probably wind in Afghanistan if we're still there in 2011.
