Saying "US foreign policy" created these groups isn't a great short hand for talking about the creation of the conditions that foment these groups. In reality it's an incredibly complicated situation where almost any action will have downsides that entail a lot of human suffering, but US foreign policy is an outsized input into that situation, so it's right to hold it responsible in turn for whatever those consequences are.
