Standard disclaimer - this is just my experience as an individual. I joined before the wars, and I can't tell you why, and I've stayed for a variety of reasons. But one of the reasons I've stayed in is all the people I served with who stayed in, fighting in those pointless wars.. I'm not a killer, so I couldn't contribute that way.
