Answer: Mikhail Gorbachev
Explanation:
In March 1985, Mikhail Gorbachev proposed policies of<em> perestroika </em>(restructuring) and <em>glasnost </em>(openness) in the Soviet Union. These seemed like policies that leaned in the direction of Western ways of economics and politics. <em>Perestroika </em>meant allowing some measure of private enterprise in the Soviet Union. <em>Glasnost </em>meant allowing a bit of freedom in regard to speech and publication. But don't get the idea that Gorbachev was trying to get rid of the Soviet communist system. He actually was trying to prop it up and preserve it, because it was starting to have many problems sustaining itself. But in the end, opening things up a bit with <em>perestroik</em>a and <em>glasnost </em>policies only pushed the USSR further in the direction of shedding the communist model under which it had lived for so long.
