ISIS on the offensive in Iraq

[Brenus]

ISIL destroyed, vanishing, imploding, exploding: End of it, all theirs "fighters" and followers becoming bands of whatever: If Russia pushes them enough, the equivalent or even less than the GIA (Armed Islamic Group of Algeria, not Gemological Group of America). dust in the win.
The French more or less succeed to do this in Chad (sorry Mali). Yes, the number are different, but so are the means that Russia can deployed. It is all depending on what Russia will be willing to deploy, and the political will.
But until now, Putin never fail about political will, and he has the backing of his Parliament.

Now, he might be happy enough to push ISIL out of almost all Syria, then let the USA & EU to deal with the left over.

I think in political terms, he already won. No one can now put Russia aside and ignore it.
The big looser in this game is of course France.
USA Obama had to meet Putin, so others leaders, even if they still, for public display, play game of words. Putin put back Assad on the agenda, and if regime change comes, it will come with/according Putin's agenda.

You do realise that ISIL has no chance to stay alive if the real power wish it to disappear, do you?
