IOW, the USA is now nothing but a brazen bully and will even bully those who were once our allies into doing the stupid things that we do. The USA is going to force everyone to break their word so that our disgusting behavior is somehow mitigated.
This is all really only a disgustingly pathetic attempt to get validation of the racist attack on a black man's legacy as President. If other countries agrees to pull out, then it can't be the racist policy that everyone says it is. The fact that we are making a blatant attempt at forcing everyone else to agree is supposed to be irrelevant. This is what they call "Making America Great Again". We were once openly racist and dealing with the rest of the world with the assumption of racist policies at play and apparently we're going to kick and scream to get the rest of the world back there.
It ought to be interesting to see how the EU proceeds, pragmatically there is very little choice for European companies, the US economy is 10 times the size of Iran's economy.
They can start reworking their economy to work with China. That way they can keep their work and not deal with the Trump Admin.
