Fight against my country? As in, be a soldier? If that's the case, the only circumstances I would fight against my country is a "damned if you do, damned if you don't" sort of thing, where they're going to blow up the earth unless I fight to stop it.
Other than that, I would chicken out and flee to a safe haven. *shrug*
