and again out of all the different forces fighting ISIS none of them want any of the others to win. Kurds, Syrians, Iraqis, Iranians, Jordanians, Saudis, Americans, Turks, and i am sure i am missing a few others. The saudi's and kurds don't want Syria, Iraq or Iran to win. The Turks don't want Syria to win. The Iraqi's don't really care about syria or vise versa. Iran is interested in Iraq, because they want to merge the countries or see Iraq become subservient to Iran. Not quite sure where the Jordanians fall but pretty sure they have a beef with Assad as well (could be wrong). Iraq has kicked us out, then begged us back. Syria has done the same, publicly kicking us out and then turning around to say we aren't doing enough. Saudis and Turks want us to start targeting the other various governmental forces. none of the nations want the Kurds to become powerful and push towards independence. we definitely have problems with Assad and Iran but thankfully no conflicts yet. Then you have to throw in the other various rebels/terrorists in the area, including the ones that for no good reason we gave money too. (this is indirectly where i agree that we are helping ISIS because they keep taking the stuff we give to non Kurds) its not a coherent fight, and ISIS is in small groups so we can never deliver a fatal blow as they are too spread out to hit all at once, and no ground force over there is either big enough, trained/competent enough or driven enough to do the job. and even if there was ONE force that was there are too many borders for ISIS to cross and get out of that force's range.
