I recently saw a guy wearing a Vietnam War hat walking around the supermarket and I realized that I don't respect most people who were part of those invasions. 

But it is tricky. Many were sucked into those battles very young. Or they needed money. Most people are good people and we need brave men to defend others. The past 50 years of American military history is pretty gross though. 

 abu ghraib, for example 

 You could just as easily be describing gangsters the same way, doing what they do because they're young and naive and needed money.
