You are such a blatant mindless partisan it's too funny. The only dumb-asses are the fools like you who spout and consume false rhetoric that places blame where it does not belong. Not that anything will stop you from eating your own bullshit vomit.
ISIS was fostered and grew into a force during the Bush occupation and the genesis of this group is entirely due to Bush's bungling in Iraq, with the aid and support of both houses which were controlled by the GOP for most of that time. Without Bush's unnecessary effort at regime change in Iraq, there would be no ISIS.
As a side note, GOP bungling like this is to be expected by people who live with an ideology that government can only get in the way and obstruct progress. Present-day GOP leaders are about as inept as the worst leadership we've seen in the past 150 years of US government leaders. If you voted for Bush and the GOP leadership in congress during that time then the blame for those slaughtered by ISIS is on your head.
Other than providing tactical support through air power and special forces, Obama has appropriately not committed significant ground troops to the area. The onus has be on the Iraqi government and other political bodies in the area to fight and reduce ISIS. Needless to say, they were unprepared for the ferocity and well funded forces representing ISIS. It's taken a while to reduce ISIS but the fight is going in the right direction and when ISIS is reduced to rubble, we will also see a new coalition in the area that is capable of defending itself from enemies both foreign and domestic. After time, Obama and soon to be President Clinton will be seen as the saviors of a situation created by GOP bungling.
