Question

which best describes why the soviet union established buffer states around its borders?○ to enlarge the country○ to protect itself from direct invasion○ to intimidate potential invaders○ to promote european integration

Explanation:

Buffer states act as a geographic barrier between a nation and potential hostile powers. The Soviet Union, having suffered massive losses from the German invasion in WWII, sought to create a defensive layer to prevent future direct attacks on its core territory. The other options do not align with the primary strategic goal: enlarging territory was not the main intent, intimidation was a secondary effect rather than the core reason, and promoting European integration was contrary to the Soviet Union's post-war sphere of influence policies.

Answer:

to protect itself from direct invasion
