With the death of former Pakistan Prime Minister Benazir Bhutto and President Pervez Musharraf under fire, Pakistan faces an uncertain future.

Now that Bhutto is gone, the future of Pakistan is up in the air.

There is hardly a more important country in the war on terror than Pakistan, and the prospect of an alliance between Benazir Bhutto and General Musharraf, two outspoken foes of Islamic radicalism, was something terrorists were determined to prevent:

Fox's terrorism analyst, Walid Phares, said, "This is a pre emptive strike they feared alot. With her in the government with Pervez musharaff as president would become a lethal combination against them."

"She has been very vocal in saying that she wants to root out Islamic extremism in Pakistan root and branch. And she has essentially set herself up as the primary enemy of the extremists," said former CIA officer, Robert Grenier.

The U.S. had encouraged an uneasy partnership between General Musharraf and Bhutto as a way of broadening popular support for a government so critical in the war on terror.

But with Bhutto's death, and Musharraf under fire, Pakistan has been plunged into an uncertain and chaotic future and only one institution offers some hope of stability.

"It has often been said and I think that it's more true now than ever before that the only viable institution in Pakistan is the Pakistani army...uh and it is really the only thing that it stands ultimately between pakistan and political chaos," said Grenier.

And a new man, General Ashfaq Kiyani, is now in charge of the army, having taken over last month from Musharraf, who was forced to resign from the military.

Analysts say General Kiyani is highly respected in military circles.

In fact, Kiyani attended commander staff training at Fort Leavenworth, Kansas

He was also a military adviser to Benazir Bhutto when she was prime minister.

But his most important previous post was as head of the ISI, Pakistan's intelligence agency, which former CIA officers see as a big advantage.

One other point about General Kiyani, Bret.

He is described as a thoughtful and soft-spoken man without the commanding presence of General Musharraf, but then a general without political ambitions isn't necessarily a bad thing because he's going to have his hands full guiding Pakistan through some very tough times.
