When the USA was attacked, the whole world sympathised with them. Even the much hated Iran allowed her territory to be used in the attack on the Taliban government in Afghanistan. Instead of the USA just doing what they had to do and leave the place they insisted on installing their own kind of government in power there. At the same time they went into Iraq on a false basis, thereby spreading themselves thinly. When Assad of Syria said he was fighting against terrorists, Senator McCain was seen going on a well publicised visit to Syria promising to support the anti government there. Arms were supplied to them and a faction of this so called opposition developed into IS or ISIL or ISIS.
