The brazen commando raid near Islamabad that left Osama bin Laden dead created agreement among lawmakers of all political stripes that Washington has gotten a minimal return on its investment in Pakistan. Conservative Republicans and liberal Democrats alike say the stunning revelation means the U.S. must get tougher on Pakistani officials.

Conditions enacted in the past largely have given the Bush and Obama administrations ample leeway in determining whether Pakistan -- seen by both as an indispensable ally in the Afghanistan conflict -- was acting as an honest partner.

Despite bin Laden's refuge being about 30 miles from Islamabad, Pakistan remains a key strategic puzzle piece for the ongoing Afghanistan war, Sen. Barbara Boxer (D-Calif.) said Tuesday. Therefore, Washington cannot afford to just cut off aid -- but it should attach "more strings," she said.

Republicans and Democrats in both chambers have called for a new approach for dealing with Pakistan, using phrases like "a very different way" and saying Pakistan too often is "both firefighter and arsonist" in the fight against extremist groups. The Hill
