Russia was not part of World War II until 1939 when they attacked Poland and it was brought to Russia when Germany invaded Russia in 1941.Given all the previous circumstances as I see one of the main goals Russia had at the end of World War II, that they wanted to make sure, they would never be attacked again by a Western European country.
I believe the answer is: Be sure they would never be attacked again by a Western European country
During the world war II, Russia faced the most damage because they are the one that become the target of the Germany's main force ( which is the strongest country compared to other members of axis power).
Because of this, they focused their effort to no longer be attacked by western European by placing many military base all across their border.
3. B, D, and E.
Hope this helps!
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.
