After world war ii, why did the soviet union take over a number of countries to its west

Explanation:

These differences were caused by the fact that, contrary to most western nations, the Soviet Union was a communist country. After the war, many nations were worried about communism spreading to other nations, and this was reflected in their relationship with the Soviet Union.

One way in which this was achieved was by conquering countries to its west, thus creating a buffer zone between itself and the Western powers.
