If we weren't a volunteer military I'm sure we'd be seeing more anti-war protest. But because the average citizen and the people aren't at risk of dieing for a BS war, they don't really care when it comes down to it. It's not that they have any chance to spending a year in Iraq.
Vietnam = draft = protest. Iraq/Afghanistan = no draft = no protest.
I joined the Army in 1997 and got out in 2007. I remember back around the time that we were getting ready to invade Iraq seeing a story on the news about a group of vietnam era combat veterans who were posting themselves out in front of recruiting stations and who were providing a counter-point to what the recruiters were saying. They were telling people what war was really about and how it shatters lives of anyone involved. I remember thinking "what a piece of shit! How could any patriotic American do that!". Geeze. I was wrong on that. I fought as an Infantryman in Iraq for 13 months and it completely ruined my life. If it becomes apparent that we are on the verge of another war like Iraq (i.e. Iran) I'll be standing in front of the recruiting stations doing just what that Vietnam Vet was doing.
I've never been one to protest or demonstrate for anything, but I'll standing in front of recruiting stations letting people know how much war sucks straight from the mouth of a broken combat veteran. I'm getting fired up and ready to go just thinking about it...
