Pakistan: Expanding Operations into North Waziristan?

Pakistani forces launched a rare attack in the North Waziristan region in the country's northwestern tribal belt Jan. 22. The strike, which coincides with U.S. Defense Secretary Robert Gates' visit to the country, is extremely limited in scope. Islamabad is trying to signal to Washington that it could cooperate against Islamist militants fighting in Afghanistan while trying not to upset its domestic security strategy.
