Pakistan's military seen moving to undercut Zardari over his close U.S. ties

Wrong, if you consider Kyani is subservient to president and constitution of Pakistan. According to you though Zardari is working under kyani rather than vicer versa. This kind of thinking since 1947 laid to breakup and disintegration.

What ever Zardar's past history is, he has done excellent job for being calm and dealing with sh!ty situation left by his predecsessor.

If army takes over in such cirmutances, I think kiss good by the remaining of Pakistan.
