Answer:
Perestroika and Glasnost.
Explanation:
At the turn of the 1970s to the 1980s, the USSR found itself in a contingency of cutting spending on wars and fostering other countries in which the communist model had established itself, such as Cuba. The war waged in Afghanistan, a country profoundly influenced by the Soviet communist power structure in the 1970s, exposed the USSR to great military weakness. Forces of Islamic resistance against Afghan "soviets" were armed and trained by the US, but they also received military aid from China (which had broken with the USSR years earlier), which led the Soviet army to successive defeats.
It was in this ambience that there was a new election in the Soviet Communist Party in 1985, in which he was elected as the new leader Mikhail Gorbachev. Gorbachev was charged with promoting far-reaching reforms in the structure of the Soviet state to ensure the regime's livelihood. However, these reforms, called Perestroika (reconstruction), whose mode of origin would be Glasnost (ie transparency), eventually opened the way for the implosion of the communist regime. As historian Silvio Pons says in his book The Global Revolution - History of International Communism (1917-1991)
