Question

Why didn't the Soviet Union vote to defend South at the UN Security Council Korea?

Answer 1

the soviet union had armed and trained the north korean army and wanted the north to conquer the south creating a completely communist Korea.

Explanation:

The Soviet Union had a vested interest in the North winning the Civil War between North and South Korea. The Soviet Union had armed and trained the North Korean army. The Soviet Union wanted a return on their investment. That return on that investment was the formation of a united Korea under communistic rule.

The UN resolution condemning the invasion of the south by the north authorized the formation of an army to defend the south and oppose the Soviet supported North Korean army. The Soviet Union had every reason to oppose the UN resolution.

The North Korean army was winning the civil war even after the UN resolution and formation of a UN army to fight for the south. Only a daring amphibious landing north of the battle zones turned the battle against the North.
