Ok. now I understand the US approach in this...
They are trying to use this stubborn idiot for the longest time. After that, they will use the card of the puppet Omar Suleiman. After that, people will get tired and will be satisifed with whoever comes from the army to implement US agenda, whether he will be Anan, or Tantawi. SO, at all the scenarios, Americans will win as long one of these 4 puppets will rule.
