From The Washington Post:

One can hear the disbelief in capitals from Washington to London to Berlin to Ankara and beyond. How can Vladimir Putin, with a sinking economy and a second-rate military, continually dictate the course of geopolitical events? Whether it’s in Ukraine or Syria, the Russian president seems always to have the upper hand.

The fact is that Putin is playing a weak hand extraordinarily well because he knows exactly what he wants to do. He is not stabilizing the situation according to our definition of stability. He is defending Russia’s interests by keeping Syrian President Bashar al-Assad in power. This is not about the Islamic State. Any insurgent group that opposes Russian interests is a terrorist organization to Moscow. We saw this behavior in Ukraine, and now we’re seeing it even more aggressively — with bombing runs and cruise missile strikes — in Syria.
