This needs to be done to help keep ISIS from doing more damage in the Mideast. The fact is that ISIS targets primarily Shi'ite Muslims, whom the group views as apostates, so this is more of a violent conflict over who's sect of Islam is the right one. This doesn't mean they don't have designs for causing havoc here in America or elsewhere in the world, as they certainly do. It's as President Obama said just yesterday, it's going to be a long struggle to deal with ISIS as they're fairly nimble, and the only way to do so is to change the psychology of the people on the ground. ISIS is more of an idea than anything else, and a very violent one at that. To deal with them effectively by taking the fight to them, we need to prop up some of the more moderate Arab states military, and this includes Jordan. Jordan is one of only two Arab nations to retain relations with Israel, so it's in everyone's best interest to up the military aid to Jordan so that they can effectively help check the brutality ISIS unleashes on everyone. This includes Sunnis who condemn their violence, as well as attempting to persecute other religious minorities who they view also as apostates.
