The Berlin Wall did not fall instantly, but the events surrounding its breaching imposed an urgent question on German leadership: what would happen next?
German Chancellor Helmut Kohl did not wait for international approval, but instead acted swiftly to propose a plan for German reunification the same month the Berlin Wall fell
Reunification was a very costly operation for West Germany, and the differences between East and West became very clear, requiring a lot of effort to regain Germany's former economic strength
Western experts were not convinced Gorbachev's economic reform program would work, as it tried to preserve too much central planning and was likely to be undermined by the unsympathetic Soviet bureaucracy
In the West, he was praised as the first Soviet leader to recognize the failings of communism, reduce international tensions, and contribute to ending the Cold War
In the Soviet Union, his reforms led to uncertainties, bolstered regional movements threatening the cohesion of the Soviet Union, and a loss of control over the unfolding events
Gorbachev's reforms of glasnost and perestroika had started a process in which he had lost control and was now merely reacting to events as they unfolded
In August 1991, hardline communists organized a coup against Gorbachev to prevent the signing of the Union Treaty, which would grant greater autonomy to the Republics
Despite the coup's failure, the Republics lost faith in the Soviet Union and Gorbachev's ability to control the unfolding events, leading to the dissolution of the Soviet Union
The Commonwealth of Independent States (CIS) was created to replace the Soviet Union, joined by 11 former Soviet Republics, while the Baltic States became fully independent
Yeltsin faced the same problems in Russia that Gorbachev had faced as leader of the Soviet Union, including high inflation, bankruptcies, increased taxes, and a rigid bureaucracy
The economic crisis in South-East Asia in 1997 hit Russia hard, and political stability only returned after Yeltsin appointed Vladimir Putin as Prime Minister in 1999
The West, particularly the US, did not want the USSR's dissolution, fearing it could lead to a return to communism, nationalism, or totalitarianism, and increase the number of nuclear powers
The USSR's collapse could trigger wars among its 15 Republics and increase the number of nuclear powers, as Belarus, Kazakhstan, and Ukraine housed former Soviet nuclear weapons
Before the USSR's collapse, President Bush established connections with the republics' leaders, and it is said he knew about the collapse before Gorbachev
Clinton initially focused on domestic economic issues but gradually pursued his own foreign policy after 1994, which led to Russia's marginalization in world affairs
Clinton and his advisors introduced the concept of "rogue states," countries that defied the new liberal world order and international law, including Libya, Sudan, Iraq, Iran, Cuba, and North Korea
The collapse of the Soviet Union brought tensions between former Soviet republics and ethnic communities within some of these newly independent countries
