Which statement summarizes the impact of the u.s. involvement in the korean war?

“The United States established a permanent military presence in Asia” would be the statement that summarizes the impact of the U.S. involvement in the Korean War since up to now, it’s still there.

To add, the Korean War began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union gave some assistance.
