Why did the soviet union see the threat to its foreign policy?

The Soviet Union perceived threats to its foreign policy primarily due to the expansion of NATO and the presence of Western military alliances that contradicted its security interests. Additionally, the ideological conflict between communism and capitalism heightened fears of encirclement and intervention from capitalist nations. The Soviet leadership was also concerned about the spread of democratic movements in Eastern Europe, which could undermine its control over satellite states and challenge its influence globally. This combination of geopolitical and ideological factors led the USSR to adopt a more aggressive foreign policy stance.
