A lesson for Pakistan: If you don't hit AQ in North Waziristan, we will

Thursday’s attacks included one set of strikes that officials said involved 10 missiles fired from five drones — an unusually heavy concentration of firepower on a single target. Officials said 15 people died in the strikes, including a well-known al-Qaeda commander named Zuhaib al-Zahibi, while one person was killed in a strike earlier in the day.

North Waziristan is the suspected home base of the al-Qaeda leadership, as well as the network of Afghan insurgent leader Siraj Haqqani, who is thought to be behind some of the most potent attacks against U.S. troops in Afghanistan.
