I think Trump is also well aware of how much his air force benefits from being stationed here.
Given his unawareness of almost everything, I doubt that.
During his last state visit, Trump was apparently surprised to learn that the UK had nuclear weapons. There aren't many nuclear powers in the world and it's kinda important for a US President to know which countries might nuke him if he pisses them off. But no, quite some distance into his term he was blissfully unaware.
