Question

which most accurately identifies the reason for the outbreak of the korean war?
the united states tried to apply the domino theory in korea to promote international cooperation.
the soviet union authorized kim il - sung to invade south korea.
the united states wanted to end communist influence throughout asia.
north koreans tried to escape the deadly virus leaked by the south korean government.

Explanation:

The Korean War began when North Korea, with the support and likely authorization of the Soviet - Union at the time, invaded South Korea. The domino theory was more of a later - developed rationale for U.S. involvement in the Cold - War context in Southeast Asia, not the direct cause of the war's outbreak. The U.S. goal was not to end Communist influence throughout Asia with the start of the Korean War. And the claim about a virus leak is a baseless and false statement.

Answer:

The Soviet Union authorized Kim Il - Sung to invade South Korea.
