Question: What institution did Fukuyama work for the year START II was signed? Passage:In August 1991, hard-line Communists launched a coup against Gorbachev; while the coup quickly fell apart, it broke the remaining power of Gorbachev and the central Soviet government. Later that month, Gorbachev resigned as general secretary of the Communist party, and Russian president Boris Yeltsin ordered the seizure of Soviet property. Gorbachev clung to power as the President of the Soviet Union until December 1991, when the Soviet Union dissolved. Fifteen states emerged from the Soviet Union, and of those states, Russia was the largest and most populous. Bush and Yeltsin met in February 1992, declaring a new era of "friendship and partnership". In January 1993, Bush and Yeltsin agreed to START II, which provided for further nuclear arms reductions on top of the original START treaty. The collapse of the Soviet Union prompted reflections on the future of the world following the end of the Cold War; one political scientist, Francis Fukuyama, speculated that humanity had reached the "end of history" in that liberal, capitalist democracy had permanently triumphed over Communism and fascism. Meanwhile, the collapse of the Soviet Union and other Communist governments led to post-Soviet conflicts in Central Europe, Eastern Europe, Central Asia, and Africa that would continue long after Bush left office.
