Its time for North America to wall up.

Canada and the US should become one country, end immigration, strictly enforce the Mexican border, and trade only with the outside world. No more foreign entanglements, no more empire, no more overseas bases. Bring the military home. Sorry parasite Israel, you are on your own, you made your bed now lie in it. Europe, you too.

Short term the standard of living will drop, people will have to do without their cheap Chinese plastic thingamajigs, but over time Fortress North America will become self sufficient.
