Myself I'd say that if you are against a war the right thing to do is to refuse to fight in it and take the consequences. Easier said than done.

But for a medic, it's a bit more complicated, because they are there to help look after the people who get damaged in that war. And while it can be said that's a way of helping the war be carried on, thta's maybe a bit too theoretical for me, when there are real people needing to be cared for.

And I don't know how the US Army works in such matters, but by far the largest number of wounded in most modern wars are going to be civilians, and I'd imagine that trying to patch up some of them might be a large part of what a medic ends up doing in this war, assuming that it can't be stopped in time.
