USA is tightening the noose around Pakistan. The final phase of attacking inside Pakistan has begun. Osama Bin Ladin was just an excuse to condition us to accept military intervention inside Pakistan. Karachi situation and water strangulation are part of the US strategy. Terrorism inside Pakistan is being managed by foreign agencies. As a first step we must evict CIAS 7000 personnel from Pakistan as soon as possible. It is a crucial time in Pakistans history.
