Singapore Prime Minister Lee Hsein Loong wrote this after Brexit, and I am pasting it here in the American context now when it looks like Trump is going to win:
"Other developed countries also face similar challenges as Britain. We all live in a globalised, interdependent world. The desire to disengage, to be less constrained by one’s partners, to be free to do things entirely as one chooses, is entirely understandable. And yet in reality for many countries disengaging and turning inwards will likely lead to less security, less prosperity, and a dimmer future."
