Settle down, Nuke Boy.

NEW YORK Feb 5 (Reuters) – It would be a “major setback” if the United States were to support either Egyptian President Hosni Mubarak or Vice President Omar Suleiman to lead a transitional government, Mohamed ElBaradei said on Saturday.

ElBaradei, a veteran diplomat and leading opposition activist, was asked about reports that Washington could support Suleiman or Mubarak to lead a transitional government. “If that were true . . . that would be a major setback, I can tell you that,” he told Reuters in a telephone interview from Cairo.

“If things that I hear today (are true), that would come down like lead on the people who have been demonstrating,” he said.

The United States signaled on Saturday that it wanted an orderly transition of power in Egypt that could see Mubarak remaining president until September, an apparent policy shift likely to anger protesters demanding he resign now.

“To hear . . . that Mubarak should stay and lead the process of change, and that the process of change should essentially be led by his closest military adviser, who’s not the most popular person in Egypt, without the sharing of power with civilians, it would be very, very disappointing,” ElBaradei said.

The adviser he was referring to was Suleiman, a leading figure in the security apparatus.
