Shortly thereafter, Russian President Vladimir Putin suspended his own commitments to the treaty. The United States had established a complex global presence in the 1990s and policymakers felt that some structure was needed to explain the “threats, interests and priorities” that guide foreign policy, but there was no agreement on how to proceed. Anthony Lake said that during this period, attempts at doctrine risked the introduction of “neo-know-nothing” isolationism or what he called “irrational” ideas. The goal of Bush Sr. and Clinton during their tenure was to develop foreign policy objectives that would support consensus rather than accelerate fragmentation within the American sphere of influence.  That the United States is increasingly concerned about the threat it sees as a revitalized Russia. In 1958, the United States launched its own satellite, Explorer I, designed by the U.S. Military led by Braun`s Missile Researcher Wernher. That same year, President Dwight Eisenhower signed a public order to create the National Aeronautics and Space Administration (NASA), a federal agency dedicated to space research, as well as several programs designed to exploit the military potential of space.
However, the Soviets were one step ahead and launched the first man into space in April 1961. Grassroots organizations such as the Polish Solidarity movement quickly gained ground with strong popular bases. In February 1989, the Polish government opened talks with the opposition, the so-called Polish roundtable agreement, which allowed elections with the participation of anti-communist parties in June 1989. The opening, initially discreet, of a border gate of the Iron Curtain between Austria and Hungary in August 1989 triggered a chain reaction at the end of which the GDR no longer existed and the Eastern Bloc disintegrated. Also in 1989, the Hungarian Communist government began negotiations on the holding of competitive elections in 1990. In Czechoslovakia and the GDR, mass protests did not occupy communist leaders. The communist regimes of Bulgaria and Romania also disintegrated, in the latter case as a result of a violent insurrection. The attitude had changed so much that US Secretary of State James Baker proposed that the US government not oppose Soviet intervention in Romania on behalf of the opposition to avoid bloodshed.  The tidal wave of change culminated in the fall of the Berlin Wall in November 1989, which symbolized the collapse of European communist governments and graphically completed the partition of the Iron Curtain in Europe.
