So the Free Syrian Army are fighting Assad but also Daesh.
Assad loyalists are also fighting both the FSA and Daesh.
Meanwhile, just about everyone is trying to kill the Kurds. Who, ironically, are probably the most effective force currently fighting Daesh.
Turkey, a NATO ally and, therefore, a de facto pal of Cameron’s are supporting Daesh while claiming they aren’t. When they aren’t busy shooting down Russian planes, of course. Russia actually are fighting Daesh but also the FSA, who oppose Russia’s mate Assad.
Saudi Arabia, big pals of Cameron and the UK government, are supporting Daesh while buying Brit arms. While beheading more people in a month than Daesh do in a year. Yet the UK supports Saudi Arabia but not Daesh and not Asad, either. Who it did support last year.
The French, of course, are on a revenge mission and don’t give a fuck who dies as long as they are Seen To Be Doing Something. And the USA, as always, is clusterfucking its way to yet another Vietnam.
Whatever and whoever is killing who, the overwhelming majority of the dead are Muslims. Killed by Daesh. While getting blamed for… Daesh.
This is the crude and simplified idiot’s guide.
Now if you can grasp that and still think that yet another party joining in the bombing of the remaining unbombed bits of Syria is going to improve the situation in any way at all, then you truly are an absolute moron.
