I figure we (meaning US and Canada) don't have the draft; the men and women who sign up for military service are doing so knowing full well what they are going in to. The vast majority that I have met are aware that the troops are there to help support the citizens, and help create the infrastructure that the governments there screwed up. They know that the risks they are taking are to help people who need it. It's awful that there is a need for them to be there, and it only takes a fanatic with a bomb to result in horrible death. But any soldier who wants out can leave. The troops need support for their choices to help those who need it in a foreign land. I know when I am sitting in my office pushing papers around, they are doing a much more important job than I am.
