Why do radical muslims hate America so much?

I'm sure that you understand that there has been a long history of agression, betrayal, and meddling on all sides. The richest, most connected countries get to control the narrative. That's the fastest and least detailed way to explain it. Also the US does desire to export our brand of democracy and freedom all around the world and some cultures find this bullying and see the US as anti religious and cultural values. Leaders in other countries sometimes use this info to rally the public against the USA and sometimes the US is guilty of the perceived transgression especially from the point of view of a religious conservative in those countries. Its complicated.
