At the end of world war ii , one of russia's main goal was to a. redesign their government as a democracy b. build a friendly alliance with the united states c. be sure they would never be attacked again by a western european country d. avoid having to join the united nations

At the end of WW2, Russia or USSR (used interchangeably) was facing what was known as "isolationism" by the pro-democracy nations, namely Britain and USA. Hence A is not their goal as they had no intent on being a democracy.

B is debatable to a certain extent. Prior to the Truman Doctrine and the Red Scare following the end of WW2, US and USSR had fairly good ties with one another. But at the end of war, the growing "red fear" from US and their fear of socialist expansionism started what we now know as the cold war. Hence B to a large extent was not one of their goals.

C is the best option since the main goal behind dividing Germany was to ensure that European nations would not challenge USSR's territory once again. And also USSR adopted the Iron Curtain policy, to counter Western encroachment and ideas.

D is false as USSR, being the "tank" in WW2 suffering millions upon million of death wanted a collective organization that would not fail like the League of Nations. Furthermore, USSR became a permanent member of the Security Council, with the power to veto any processes.

The answer would be limited.
