That's really a shame. Bhutto was the best hope for democracy in that country. Pakistan is in trouble now -- and, by extension, we're all in trouble.
We may have to go in there and secure their nuclear facilities if things start to deteriorate further in terms of civil unrest. And that's coming from a guy that's been opposed to the Iraq War from the beginning. But Pakistan is a different situation. You've got the Taliban and al-queda (The real one, not the Iraqi ripoff) in the northwestern foothills, trained by the CIA in the 1980s. The country as a whole is fairly moderate as Islamic countries go nowadays, but if these extremists, who already have a paramilitary operation, topple Mustaraff, there's no saying they couldn't impose minority rule. And I don't think I have to tell anyone what al-queda would do with a nuclear weapon -- especially if they feel they are only temporarily in power in a given place.
The ideal would have been a smooth handover from the current regime to a new regime backed by the liberal student and lawyer protesters who are in the streets. But they are without a prominent leader now, and the other two potential factions (The Islamic fundamentalists in the northwest and the military government, which is what the government there has become) have all the weapons.
