That's Krauthammer's matter-of-fact invitation to Americans take the old Sunni-Shiite division to heart as the continuation of the old-but-less-old Cold War. The column is called "The fruits of epic incompetence," blaming Obama and Kerry for giving Putin the opening:

And Obama gets to slink away from a Syrian debacle of his own making.
A lot of people have wondered why Russia and Syria seem to be working to throw the Obama administration a lifeline.

Sacrificing them to end the threat the U.S. poses to his regime is more than worth it to him.
