Every country in the world needs all the other countries more than all of the other countries need it. There’s just no real leverage, because we’re all interconnected; you can snip one country out, and it’ll slightly hurt everyone, but it’ll *wreck* the country that was snipped out.

This is just such an absolutely perfect summary. I wish we could American politicians to speak this clearly to explain why this is such a bad idea.

they take a hard left and blame minorities somehow

Or a hard right, maybe?
