What victory does to Hamas is to put the movement into an impossible position. As preliminary reports emerge, Hamas has already asked Fatah to form a coalition and got a negative response. Prime Minister Abu Ala has resigned with his cabinet, and president Abu Mazen will now appoint Hamas to form the next government. From the shadows of ambiguity, where Hamas could afford--thanks to the moral and intellectual hypocrisy of those in the Western world who dismissed its incendiary rhetoric as tactics--to have the cake and eat it too. Now, no more. Had they won 30-35 percent of the seats, they could have stayed out of power but put enormous limits on the Palestinian Authority's room to maneuver. By winning, they have to govern, which means they have to tell the world, very soon, a number of things.

They will have to show their true face now: No more masks, no more veils, no more double-speak. If the cooptation theory--favored by the International Crisis Group and by the former British MI-6 turned talking head, Alistair Crooke--were true, this is the time for Hamas to show what hides behind its veil.

As the government of the Palestinian Authority, now they will have to say whether they accept the roadmap.

They will have to take control over security and decide whether they use it to uphold the roadmap or to wage war.

There will be no excuses or ambiguities when Hamas fires rockets on Israel and launches suicide attacks against civilian targets. Until Tuesday, the PA could hide behind the excuse that they were not directly responsible and they could not rein in the "militants." Now the "militants" are the militia of the ruling party.
