There are always going to be people who are willing to use violence to get what they want, including violence against the USA. Sometimes an all-volunteer military is enough to keep them at bay, and when that's the situation, snowflakes won't need to put themselves in harm's way to keep the rest of us safe. But there are times that that's not enough, and we need to build our forces up to a higher level than that can manage. When that happens, some of us will be picked to defend the rest of us regardless of what they want so that this nation can survive. That's why veterans get extra points in Civil Service exams, get subsidies to pursue their education and medical care for the rest of their lives: to repay us for our sacrifice. If you don't think that's appropriate, you must not think very much of your country.
