Firstly you can't assume that 1% equates to 1% within every population.. it doesn't work like that which I suspect you know! From what I understand that 1% pretty much includes any country which is considered to be an enemy of the west, such as Iran.. I don't think all Iranians are quite ready to call themselves terrorists quite yet.. also from recent studies that support is more like 7%.. and support doesn't automatically equate taking action.. I support gay marriage but I'm planning on becoming gay due to that support! I'm not suggesting there isn't an issue.. I'm not suggesting there aren't Muslims in the US and every other western country ready to commit some form of terrorist act - I am saying your numbers are wildly over the top & are the sort of scaremongering nonsense that Trump would spout!
