End of the Cold War

The Cold war finally drew to a close when the Soviet Union collapsed due to the perestroika and glasnost reforms introduced by their leader at the time, Mikhail Gorbachev. The Soviet Union was suffering from economic difficulties, including financial strain and constant 
pressure from the United Nations and US. 

Even though it was a long, stressful, and intense situation for over 45 years, looking back on it now, some of the technology we have today most likely wouldn't exist today had there not been the competitive nature of the USA and USSR and the need to create in order to prove their superiority. 

In conclusion, the war happened. And the USSR lost. The end.
