What is the difference between the Korean war and world war 2?

The Korean War (1950-1953) was a conflict primarily between North Korea, supported by China and the Soviet Union, and South Korea, backed by United Nations forces led by the United States, focused on the ideological struggle between communism and democracy. In contrast, World War II (1939-1945) was a global conflict involving many countries across multiple continents, primarily between the Axis powers (including Germany, Italy, and Japan) and the Allies (including the US, UK, and Soviet Union), driven by territorial expansion and ideological clashes. While World War II led to significant geopolitical changes and the establishment of the United Nations, the Korean War solidified the division of Korea and heightened Cold War tensions.
