<reasoning>

Analyze the historical context

The Korean War began on June 25, 1950, when North Korean forces crossed the 38th parallel.

Evaluate North Korean assumptions

Kim Il-sung believed a rapid invasion would unify the peninsula before the United States could react.

Assess US foreign policy signals

The US had recently withdrawn its combat troops from South Korea. Furthermore, in January 1950, US Secretary of State Dean Acheson delivered a speech defining the American "defense perimeter" in the Pacific, which excluded both Taiwan and South Korea.

Connect to the options

These signals led North Korean leadership to strongly believe that the United States would not intervene militarily to protect South Korea.

Eliminate incorrect options

• The US was not distracted by other major wars in June 1950.
• Stalin did not promise full military support; he only authorized the invasion on the condition that Soviet troops would not directly fight US forces.
• North Korea was decades away from developing atomic weapons in 1950.
