idk, I have a hard time taking any poll of Americans seriously when it comes to foreign policy in general and Palestine/Israel in particular. Talk to any American for five minutes about the wider world and you’ll quickly realize you may as well be talking to a beagle.
Even when they are honest and can admit they don’t actually know what’s going on in other countries, they will still feel they are entitled to have an opinion on it and that their opinion is correct.
