IRAN SHOOTS DOWN PASSENGER JET AND IGNITES CRIES FOR RETALIATION; ROGER REES, CHRISTOPHER LLOYD GUEST-STAR —

On Valentine’s Day, an Iranian fighter jet accidentally shoots down a British passenger plane — killing 100 people — but C.J. (Allison Janney) is reluctant to awaken the President (Martin Sheen) even as the hawkish British prime minister considers bombing Iran’s nuclear reactors in retaliation. After learning that the passenger jet was mistaken for a U.S. spy plane, Bartlet calls in British ambassador Lord John Marbury (guest star Roger Rees, “Cheers”), as they debate whether a strike is the perfect excuse to wipe out the atomic sites or if it will set back reform movements in the rogue nation. Elsewhere: Abby (Stockard Channing) and C.J. war over the President’s schedule for rest; Toby (Richard Schiff) and a legal professor (guest star Christopher Lloyd, “Taxi”) try to pound out a new democratic constitution with representatives of Belarus — and everyone keeps dodging the traditional White House appointment with Miss Universe.
