Leaders who have been installed and supported with the help of the West.
Iran, Syria, Saudi Arabia and Jordan are all ruled by regimes that are either anti-Western or pre-date Western involvement in the area.
A number of countries that are allies of America get significant American investment but that doesn’t make them puppet states (if it did then we’d have to qualify as a puppet state as well). This sort of clientism has gone on in the Middle East since Roman times. In the Far East it has gone on for much longer.
America happens to be the strongest kid on the block at the moment. Eventually it will be someone else and they will exert their power in order to influence events to suit them. That’s the way it’s been for thousands of years and that’s the way it will continue to be. Anyone who thinks otherwise is either very naive or very... sheltered.
The question is what boundaries the dominant power works within. In the case of America it is usually far more restrained than the other big kids on the block, but there are notable exceptions. The high water mark of US intervention/imperialism was over 100 years ago. The two most despicably aggressive and unjust wars they ever fought were against Mexico (Texas and New Mexico) and Spain (in the Philippines).
