World War III or Armageddon in Syria & Iraq?

The UK is planning on deploying more warplanes to Syria, Russia is talking about deploying 150,000 ground troops, the US has sent 200 special forces (& who knows how many mercenaries & CIA operatives). Yet there is reportedly no collaboration between any of them, except between Israel & Russia, to avoid incidents like the shooting down of the Russian war plane over Turkish air space. What can possibly go wrong?
