A nuclear device is tested in the Indian Ocean, but none of the known nuclear powers will claim responsibility, leading to the possibility of a terrorist group holding missile tests. Vice President Russell, heretofore dismissed by west wing staff as a joke, a four-term congressman alleged to be securely in the pocket of a large Colorado mining company, recalls a junket he'd taken early in his political career in which a drunken Israeli statesman confessed to secret missile tests. Russell visits the sit. room and puts the military and national security leaders at ease, leading the president and Leo to reassess the man's political gravitas. Bartlet then drags the Israeli p.m. to the White House, where they debate the power of the U.S. to dictate which states should have nuclear capabilities.

Josh maintains a vigil beside Donna's bed in hospital, and needles Colin over his background and relationship with Donna. President Bartlet is determined to reject the unanimous demands of Congress, the American public, and his entire staff to retaliate for the roadside bombing. Leo tries to find a way to talk the President around while Kate tries various long-shot attempts at getting the Israelis and Palestinians to negotiate at Camp David.

Josh returns from Germany in time to voice concerns about Leo; the Israelis and Palenstinians meet at Camp David with little chance of an agreement; the President and Leo's differences over the Middle East crisis reach a breaking point.

Leo is found in the woods and rushed to the hospital; the staff struggle to hold the peace deal together without a Chief of Staff; the President neglects his duties out of loyalty and guilt towards Leo; Donna arrives back in the USA.
