For everyone in the world outside the US starting up the isolation process...remember how well that worked in the 1930's. It left tens of millions to die, turning back refugees sent them to their deaths, and fascism still came for their countries anyway. Isolation & abandonment is not a great policy. The world is even more globalized now than it was 100 years ago. The faster we realize we can rise or fall together, the better off everyone will be.
Politics can be complicated, but empathy is not. Empathy demands that we look at what is going on in all oppressed nations and peoples, and bear witness. And no one with empathy can then refuse to help. This is why empathy is being made to be the enemy. This is why individualism is being touted.
So. Let's all climb out of this pit now, and together, as the people of the Earth.
