The formation of ISIS is more Obama's fault. They have formed in response to Obam'as attempts to topple Assad. With US and UK encouragement they have grown and been a draw for every fanatical jhadist dreaming of creating Islamic republics where stable dictatorships once ruled. The US and UK had a fantastic opportunity in Syria and they blew it big time.

Totally disagree with that assessment. For once, the US actually did the right thing. Rather than becoming embroiled in a civil war and risk being accused of meddling, they took a step back and allowed matters to take their course.
They let Assad's neighbours try and reason with him, let the Arabs have autonomy for once.
When that failed and allegations of chemical weapons use was discovered, he was prepared to act. But then, as ever, the Russians chucked their oar in and accused the West of acting like playground bullies(with no little backing from the foil hat adorned bedwetters) so again Obama stepped back and said ok, have it your way.
Obama is damned if he does, damned if he doesn't and as usual, pathetic attempts and sheer inaction by Arab neighbours and leaders has allowed a despot to continue unabated.
