What tactics, strategies, and achievements make him a failure?

If we go by an op-ed written by some guy, the fact that he didn't restore relations with Moscow and Iran in 8 months? "grizzled [unnamed] Democrats" think he's a pushover? "some" talk about how he's like Carter?

I like how he acts like running Harvard Law Review is a walk in the part, let alone the fact that it's the only thing he managed.
