policy can always be undone
I have heard from most of my friends that Obama was the worst President for ISrael. Yet these same friends extoll the virtues of Trump, and how Israel is in the best position it has ever been.
Changing character is much much harder. Trump has had a corrosive effect on Americna politics, undoing it is much harder than undoing any policy that you dont like. 4 more years of this would make it almost impossible to undo
