In the case of the collapse of the Soviet Union, it can be viewed from a realist approach. Before Gorbachev instituted perestroika and glasnost, the Soviet Union was already in the throes of decline. The reforms were supposed to return them to super power status, but proved the undoing of that nation through circumstances such as the Berlin Wall coming down and the loss of the Eastern European bloc of nations. However, Gorbachev cannot be blamed for the entire dismantling because the Soviet Union was already experiencing problems keeping up the United States as far as economically. Therefore, their form of government could not continue to go on with a centrally controlled economy.
What also hurt the Soviet Union was the war in Afghanistan. It was draining even more of their resources they needed to maintain military parity with the United States. It was simply
inevitable that socialism or communism would eventually fail by not delivering a strong enough economic backbone for the Soviet Union to survive.
