Pakistan stability

The Taliban are suddenly threatening to take over Pakistan. There are three reasons for this: 1. The weakness of the current Zardari Government. Since Pres. Musharraf was forced to resign, Pres. Zardari, the widower of Benazir Bhutto, has failed to consolidate his power and control over Pakistan. 2. The growing power of the Taliban and their Al Qaeda collaborators, which have consolidated their position in the northern areas that have never been fully under central Government control. They now contol the Swat Valley and recently captured areas only 120 km north of the capital Islamabad, but then withdrew under an agreement with the central Government, that was more of a political withdrawal than a defeat. 3. The inability of the US and NATO to expand their fight against the Islamist extremists into Pakistan, due to refusal by the Pakistan Government to allow their entry.
While the NATO allies fight the Taliban in Afghanistan, they are able to recruit, train and rearm their forces in Pakistan. This is an untenable position for the allies, since they face a growing threat from the Taliban in Afghanistan and there is an increasing fear that the Taliban and Al Qaeda will take over Pakistan. If that happens it would be a game changer, because then the Taliban would have control of the Pakistan nuclear weapons. However, as all political vacuums get filled, so if the Taliban move in to take over the vacuum left by a weak Pakistan Government, so then India would be motivated to move in to neutralize the Muslim extremsists.
It is well known that there have been forces in Pakistan that have been supporting terrorism against India, the latest outrage of which, the massacre in Mumbai, was clearly planned and launched from Pakistan by Pakistani nationals. During the origianl Taliban uprising in Afghanistan the Taliban were supported and supplied by the ISI the Pakistan intelligence service. However, when Pres. Bush gave Musharraf an ultimatum after 9/11, he changed direction and became an ally of the US. However, this was going against the usual direction of Pakistan policy which has been anti-Western and anti-Indian. Now that the Zardari Government is failing to control the extremists, he is making deals with them, for example allowing the introduction of Sharia law into the northern tribal regions.
It is likely that under these circumstances the Islamist terrorist threat to Afghanistan and India will dramatically increase. Ultimately the allies will be forced to act. If it seems that the Taliban are in danger of taking over Islamabad and having control of the nucelar weapons, then it is likely that India will be forced to act.
When asked what the US would do under such circumstances Secty of State Clinton said today that she hates to think what would happen. It is hoped that the State Dept and the Obama Administration have a clear strategy if that transpires. To "lose" Pakistan would be even worse than the "loss" of Iran that came under the Carter Administration and was the beginning of the development of the greatest threat to the West since Fascism and Communism were defeated.
