Notes:
The map I used didn't include Turkey (US ally) or Gaza as part of Palestine. Palestine and Lebanon are the only countries that have only been attacked by Israel and not the US directly. Pakistan is technically a US ally and Lebanon has security agreements with the US, but neither host US troops.
For every single country in the oil-rich Middle East, the options are to let the US troops come voluntarily, or to fight them off when they attack.
I did another version for China btw:
Its always funny when people try to impute the imperialistic actions of the US on its enemies. The US as the west's leading country is world capitalism's cop since the end of WW2, and has ~800 military bases outside to project power outside its borders.
By comparison, all other countries combined have only ~30.
Is it right to assume that the USA just refuses to leave once they have established a base?
Unless they are forced to, yes. There are so many local scandals with these US military base countries also, especially in Japan, SK, Italy, and the UK, where the troops commit various local crimes like rapes and murders, but are then sent back to the US to avoid being punished.
