Five years ago: The U.N. Security Council unanimously denounced Israel’s deportation of more than 400 Palestinians and demanded their immediate return. Kim Young-sam was elected South Korea’s first civilian president in three decades.

One year ago: FBI agent Earl Edwin Pitts was arrested, accused of selling secrets to the Russians. (Pitts was sentenced in June 1997 to 27 years in prison after admitting that he’d conspired and attempted to commit espionage.)
