I'm a Norwegian citizen, and I feel like it's easier to fight for my country in self-defence. We've been occupied before, during WWII, and I'd like to think I would fight for my country in a case like that.
If Norway starts a war, on the other hand, I'm a little more reluctant. We have very few reasons to be aggressive, if any.
The only way I can imagine Norway joining a war is through NATO, if the U.S. starts something. Now, imagine, if even you're reluctant to fight for the U.S. as a U.S. citizen, how I would feel fighting for a U.S. cause. Fuuuck that. Your government is a circus and I'm not dying for Trump.
