Yeah, yeah--it was a quagmire and all that: I hear the same thing today from the same people about our current war.
Every war was like that and every war will be like that. It is by definition a sordid, stinking thing....
Guess what? We are still going. We are still volunteering. We are still winning.
Good thing, too. I'll bet you'd like living under Sharia about as much as the Southeast Asians enjoyed the Killing Fields.
I don't know what planet you were on in 1970, but Viet Nam was *nothing* like Iraq, and Iraq is nothing like Viet Nam. Militarily or politically.
Any similarities are in the minds of middle aged leftists and media people that hate the miltary.
