I think "the United States' overreaction to 9/11" would need to be broken out into much finer detail. * Referring to Iraq, there's a good argument to be made that it wasn't so much an overreaction as a seizing of opportunity. * For violence against Muslims in the USA there was some of that, but I don't think it was either widespread enough or widely accepted enough to be considered a reaction by "the United States" * For immigration policies, maybe, though again I think it's pretty clear that that's more to do with political parties than a US-wide reaction.
