US pulling out of the JCPOA was the biggest travesty of the 21st century. No nation state will ever feel safe without a nuke now.

But Israel wanted to destroy Iran as competition. And they got it.

Agreed. And I'd say pulling out of the TPP is an equivalently big mistake, and will honestly have far worse consequences for the US but in far different ways. Letting China be the leader of the Pacific by pulling out, in combination with the terrible hostility to all countries there now, especially to South Korea, massively weakens the US economically and military. We just handed everything over, no fight, no fuss, no benefit to the US. Ugh.
