If spring has put a song in your heart and the absence of cynicism and pessimism has you disoriented, John Pilger’s Death of a Nation: The Timor Conspiracy should set you right. The British journalist’s documentary about the 1975 Indonesian invasion and ongoing occupation of the former Portuguese colony of East Timor chronicles not only the bloodcurdling atrocities committed by the invaders (the percentage of the population killed is actually higher than that in Cambodia under the Khmer Rouge) but the active complicity of the U.S., Australian, and other Western governments. At noon & 2 p.m. at the Biograph, 2819 M St. NW. $5 (benefits D.C. East Timor Action Network). (301) 589-9071. (James Lochart)
