yes, now is a big mess. from what saw on tv, her supporters think 穆沙拉夫 should be responsible for her murder. i guess that is exactly what al qaeda wants. on stone kills two birds...
if al qaeda took over pakistan, it would form a big threat for the west part of china.
al qaeda seems to seek a place to build a country based its version of islam. at least al qaeda seem to be seeking a base for its long term fight with the west. china might not be a major target at this moment, but maybe in a long run.
