I think the point is that the protesters don't see enlisting the Army as helping their cause. I think I saw that piece, or similar pieces at least about the same sentiments from US military personnel. I've also seen the flip side of that coin, too.

Consider who affected US military operations more: the people who accepted the draft and went, or the people who fought for what they didn't believe in and made it that much more difficult to attack other countries in the following decades.

I'm not asking which side is right, but they both affected the foreign policy in one way or another. I'm just saying that you don't have to join the military to effect it.

No, in case you're going to ask, I refuse to do either.
