The west main culpability was just handing over control to people that were not capable of running a country. We should have been tougher in the beginning.
Although the mess in Africa and the ME was more of European doing than the US, the US seems to get a lot of the blame which seems unfair as they only benefited from slavery not from colonial occupation.
I agree. US does tend to get the blame, when in fact, Portugal and Spain were the forerunners of European slavery and left behind the worst colonies.
