As far as I know there is no other country that will let me bring my FN-FAL and a 1911 with me when I move. Therefore, I'm not considering moving.

In the case of the Jewish folks in Europe, there was a chance to flee for those that could afford it and those that believed it would get as bad as it got. Pretty tough to break up families, and leave everything one has built. And there are some that probably just figured it was worth the apparent risk. Hopefully we'll never see that here.
I have personally met refugees from Communist Hungary, Romania and Poland. The families from Hungary and Romania actually escaped from behind the Iron Curtain by nefarious and dangerous means. Incredible stories. All were charged and driven folks with no illusions about what is in the USA. Interesting.
Guess I'll just stick around the USA. Boston is right, it's going to be interesting here, why miss it? We have charged and driven folks right here.
