Yep, that's pretty much sums it up!
Trump is easy to predict. Consider whatever the objectively right, moral, and/or decent thing to do is in any given situation and Trump will do the exact opposite of that. Every time. Without fail.
He's a jackwagon, but any president would have been ok with this too and also supported Saudi Arabia and demonized Iran. Have we forgotten about the supposed hijackers on 9/11 who were Saudis? The Bush Family has a connection with the Saudis. Every president follows establishment rules when it comes to the Saudis. The U.S. and SA offer each other services. The U.S. supplies the muscle and propaganda while the Saudis supply regional support in the Middle East. As long as the U.S. needs SA for it's oil wars and petrodollar prop up, it will do nothing even if the Saudis rounded up 100 Americans in Times Square and chopped their heads off.
