Standing at the White House with President Pervez Musharraf today, President Bush said he was "taken aback" to learn that a US official threatened Pakistan after September 11. Despite that warm embrace, there are serious questions about what's been called a crucial alliance in the war against terror. Afghanistan has complained that Pakistan's recent deal with tribal leaders is a green light for the Taliban. Musharraf took power in a military coup and he's now caught between a drive for westernization and Islamic extremism. Pakistan is getting massive amounts of American aid, but will his divided country allow Musharraf to be a reliable partner?
