According to whom?
You: by whom?
By a segment of the population that didn't like the war and didn't want their loved ones fighting it. There was another segment of the population that took it as a matter of patriotism to serve and not question the government's intentions. That's why the lottery came along. People were so disgusted with those profiting from VN and voting for it were finding ways for their loved ones to avoid it. It wasn't long after the lottery came in that the war ended.
What I don't like is the double standard....Quayle and Trump get criticized for not serving; Gore, Clinton, and Romney (to some degree) got a pass. Selective outrage benefits no one.
I still have to ask my question that no one brings up. What happened to McCain in VN was horrible, for sure. So why is he all for war-mongering in the Middle East? Think of all of the deaths and hostages and broken lives that have occurred at our hands in Libya, Syria, and Ukraine etc.....with McCain's enthusiastic support.
