Step-by-step explanation:
The Soviet policy of glasnost helped contribute to the end of the Cold War by exposing the weaknesses of the Soviet government and its lack of international influence. This increased transparency allowed people to see the economic and political problems within the Soviet Union, which eroded its power and credibility. Furthermore, glasnost helped ease tensions with Western countries by allowing for more open and honest communication, leading to diplomatic negotiations and arms control agreements.
