Personally, I think a tough, no nonsense skilled diplomat like John Bolton is needed there. West is more suited to be the next Secretary of Defense.
There is a story about Kissinger that he brought all the department heads into his office one at a time and showed them a globe. He then asked them to point out their country. When they pointed to Yemen or France or Argentina, Etc. He would turn to the US and say “This is your country and don't forget it!”
That's what a diplomat does.
An Alan West would say “The United States is your country! Now pick up your last check and don't let me ever see you again!”
I completely agree.
