Describe the policies Mikhail Gorbachev proposed to strengthen the soviet union's role in the world. (perestroika, glasnost)

Mikhail Gorbachev tried to make the Soviet Union more decentralized and slightly more liberal, but instead of success, it ended with disaster.

Explanation:

Mikhail Gorbachev was the last president of the Soviet Union. Unlike his predecessors who were much more dictator-like, he was a politician who had a vision of transforming the Soviet Union into a modern and progressive nation gradually. He attempted to achive the policies of perestroika and glasnost, but he failed badly.

Perestroika was a policy that was intended to reform the stagnant command economy, modernize it and make it more open. Glasnost was a policy that was decentralizing power and gave bigger power to the leaders of each Soviet state. While this was with good intention, the end result was a catastrophe, with the Soviet Union entering a big crisis and collapsing. The reasons why these policies failed were the fact that the Soviet society and the political elites were not prepared for it nor they seemed to be willing to change, as well as using the situation by the leaders of the states to gain more power and move away from the state, thus creating tensions.
