Tensions are rising between Pakistan’s civilian leaders and its generals over a memo that accused the army of plotting a coup after the U.S. raid that killed Osama bin Laden in May.

“Who isn’t fed up with Zardari? It’s not just the opposition and the man on the street but people within the government too,” said one military source who asked not to be named.

“But there has to be a proper way. No action is being planned by the army. Even if we tried, it would be very unpopular and not just with the government and the opposition but most Pakistanis too.”…

But the army remains the arbiter of power and analysts say it has plenty of ways to pressure Zardari to step down, especially if a link is established between him and the memo, which sought the Pentagon’s help in averting a feared coup.
