Answer:
The collapse of the Soviet Union resulted in the creation of multiple new countries in Eastern Europe and Central Asia. A potential problem of this was the rise of nationalism and expansionism.
Explanation:
The Soviet Union, even though heavily centralized, was actually a federation of numerous states, with Russia being the absolute owner of power in it. As the Soviet Union started to fall apart, multiple of these federal states managed to gain independence, thus changing the map of Eastern Europe and Central Asia by creating numerous new political entities.
wOne problem that was a potential problem, developed, but still haven't made a big problem was the rise of nationalism and expansionist politics. Many countries wanted to have territory that belonged to other countries because they thought that it belongs to them traditionally. Luckily, most of these tensions have been sorted out diplomatically, with the only incidents occurring in Central Asia, mostly because of Uzbek aggression toward Tajik and Kyrgyz populations.
