PG - I'm definitely not going to act as a recruiter here, but I'll try to answer your question as best I can. Yes, it is allowable to have a stance on that issue. I ususally don't, because I really don't have a stance on that issue, and here's why. In my opinion, only you yourself can tell you if you want to serve. No one else.
For some people, it's just a job, and those people tend to be pretty miserable in the military. Would you put your life on the line just to pay back your college loans? When I came to the Air Force Academy, the only thing that kept me going through the first year - the toughest year - was that I was getting a free college education out of it. And I was pretty miserable. After that year, though, I realized that service in the military - especially as an officer or senior NCO - was more along the lines of a calling. And quite frankly, I don't really understand it. I don't know why I'd ever want to give up my life for a bunch of people who could care less about my existence. But this is what I do, and it makes me happy for some reason.
Anyway, enlisting (or entering an officer training program) is definitely not a requirement for supporting a war. If you really feel that giving your services is the best way to help out, then go for it, soldier. But if we all went off and enlisted, there wouldn't be much of a country left to defend. I don't know if I'm making a whole lot of sense right now - it's pretty early and I just woke up. Assuming that you're an American considering enlistment, I'm certainly not going to push you one way or the other - it's your life, and your decision.
