That there will be a coup, is unlikely. DD has aptly reconstructed the whole scenario, and why the drama is being enacted.
To provide context to all this...
Imran Khan is being projected as a PM candidate by Pak Army backing.
Memo-gate controversy created by PakArmy/ISI to beat the PPP govt.
Zaradari goes to UAE citing health reasons to see what comes of memo gate controversy.
PPP govt. take tough stand against PA/ISI in Memogate controversy.
General Pervez Kiyani went to China on a 6-day trip perhaps to indicate the impending elections
Pervez Musharraf prep ones his arrival to Jan 27
Pak Supreme Court calls Pak PM a liar and threatens to disqualify him
Urgent PPP core committee meeting assembled to discuss this issue
All this indicates that General Elections are impending in Pakistan with Imran Khan projected as a PM material with Army backing.
Pakistan's judiciary slept over this whole episode till the time IK effectively appeared on the scene, and seemed to be in a position to make the most of the opportunity coming his way.
Its elections coming soon, IK will be the next PM, sitting alongside the MQM's, APML's. At best, term it a soft coup because what is to happen is already scripted, with direct involvement of pa, though covertly.
The interesting thing is, PPP doesn't want to go down without a fight, and well, if one looks at it, that is the only way they can make sure they win enough seats in the next elections, wont be surprised if one gets to see a repeat of 07-08 when people were on a rampage post Benazir's assassination in Sindh, people on the streets were shouting Shindhudesh, and zardari then was forced to give the slogan, "Pakistan khappay".
