Is the world expecting too much of its anointed messiah?

Quamrul Islam Chowdhury, a U.N. climate conference delegate from Bangladesh, says “the world expects a lot from President Obama” and that he “should make sure he does not disappoint the world.”

But it will be almost impossible for Obama not to disappoint the world when he arrives here next week — in large part because the world keeps ratcheting up the expectations on him…

But Obama really can’t commit the United States to much in Copenhagen because the senators he needs to pass a climate bill aren’t on board with the kind of greenhouse gas restrictions that the EU and others expect.

“[Obama’s] going to lock himself in at a number that is not a number that we here in the Congress should adapt in legislation,” Sen. Lisa Murkowski (R-Alaska) predicted in an interview with POLITICO last week.
