The reforms he underwent in communist Russia slowly offered the American Administration the hope that communication and cooperation would be possible and that an end to the communist regime was in sight. Thus, perestroika and glasnost became the tools with which the Russian leader also earned Reagan's trust. (Hyland, 1990) the Reykjavik summit, although ended with no important outcome, represented the first proof of the reevaluation of the relation between the two superpowers. It all culminated however, in the Malta summit, when the two leaders Bush and Gorbachev declared the Cold War over. Overall, it can be said that the Vietnam War was indeed an important moment in history because it offered the conditions for the U.S. To realize the change...

From this point on, subsequent administrations worked, more or less, to reaching a peaceful outcome to the cold war.
