For many in the US, the notion of such radical change often is reduced to the question of whether or not to talk to Hamas. That is a diversion. The challenge is whether Obama can speak to those for whom Hamas speaks. They are the people who have lost faith in America, its motivations, and every proposal it promotes.

The broader point is this: a window exists, short and subject to abrupt closure, during which President Obama can radically upset Palestinian, Arab, and Muslim preconceptions and make it possible for his future plan, whatever and whenever it might be, to get a fair hearing—for American professions of seriousness to be taken seriously. It won't be done by repackaging the peace process of years past. It won't be done by seeking to strengthen those leaders viewed by their own people as at best weak, incompetent, and feckless, at worst irresponsible, careless, and reckless. It won't be done by perpetuating the bogus and unhelpful distinction between extremists and moderates, by isolating the former, reaching out to the latter, and ending up disconnected from the region's most relevant actors.

It won't be done by trying to perform better what was performed before. President Bush's legacy was, in this sense, doubly harmful: he did the wrong things poorly, which now risks creating the false expectation that, somehow, they can be done well.
