ELI5: Did the US really create the Islamic State, and if so, why?
gpt
When people say the U.S. created the Islamic State it's not like the U.S. went to Iraq and recruited people to be in this great new ISIS thing.

They mean that the U.S.' actions in the Middle East (specifically toppling Saddam) were the impetus that lead to the rise of groups like the Islamic State.
