Yes, Syria is a gambit that allows Russian client Assad to recover his country. The opposition on the ground is a joke waiting to be rolled up in a surge. We are now having the surge. Do not be surprised to see Russian ground troops.
If you permit a vacuum, it becomes necessary for someone to fill it. That has typically been the USA if anyone really cares. Remember Somalia? Here we allowed a vacuum and that allowed ISIS and the faux revolt against Assad which had to be the most ill thought out sponsorship ever.
Now Russia has seen fit to end it. Instantly the USA got their proxies out of dodge and left their erstwhile rebels in the lurch. The ill begotten policy entered in stealth is been left in stealth. Had the USA intervened the picture would be the same.
No one is going to repeat the USA folly of trying to run the place after knocking over the military threat. I think even the USA is cured.
