Anybody wanting to lampoon the Obama presidency is out of luck — there is no way to top the real thing. From being outmaneuvered by Russia to erasing red lines in Syria and getting snubbed by Iran, September was the cruelest month.

That’s only half the bad news. For as small as the president looked abroad, he looked downright childish at home.

He is following his failure to negotiate successfully on the world stage with a refusal to negotiate at all at home. His message to Republicans on both the debt ceiling and ObamaCare is the same: nyet, nyet.

Call him confused about who the enemy is.

The dynamic is startling. The more the world pushes Barack Obama around, the more he pushes back at home. It reminds me of a Mort Sahl joke from the Cold War: Every time the Soviets lock up an American, we retaliate by locking up an American.

And so Vladimir Putin and his evil spawn in Syria and Iran can mess with Obama all day long, but House Speaker John Boehner can’t get the time of day from him.

Our president is Caesar here and Chamberlain there. That is the real Obama Doctrine.
