I rather think that if you read the history of the last 100 years of western involvement in the Middle East and North Africa you would find that various western countries imposed assorted puppet kings and dictators on those countries so as to maintain western influence there for assorted financial and geopolitical reasons.So you would find that western countries created metastable political systems extending from Marrakech to Mosul that would in all eventuality fail as these systems had no respect for the wishes of the people who actually lived under them. And failure of political systems leads to civil wars until something stable develops.
As for the USA freeing people; when did that last happen? Like most empires, the USA acts out of the self-interest of those who run the empire. At least we Brits built railways and infrastructure and developed education and hospitals, rather than simply bombing the places we conquered back to the Stone Age, and we got out reasonably peacefully when the time came to go.
