A piece by Ian Bremmer that makes the point that lack of action on Syria shows shifting world order.

He concludes:

This G-Zero problem will not last forever. Eventually, the political wildfires that are allowed to burn out of control will threaten enough powerful countries to force a certain level of cooperation. Unfortunately for Syrians, their suffering alone will not be enough.

 

Which unfortunately for the long-suffering Syrian people, means the US should not weaken itself by getting involved. The US should conserve its energy and look inward to rebuild.
