Teribus strangely you don't seem to get the point of my last post.

To allow Assad's troops to move forward to engage IS fighters hopefully weakened by Russian air strikes, the anti Assad terrorist have to be defeated.

What is the point of striking against IS positions if there is no ground attack to follow up? .....That is what the US was doing and it failed miserably.
Why would President Putin wish to defend IS. Russia is in grave danger from Islamic fundamentalism

I would be interested to hear YOUR views on how these fundamentalist maniacs are to be stopped.
