Who enforces decisions made by the Security Council?

(U.N. members which volunteer?

The United Nations does not have a standing military force equipped with battleships, bombers, and millions of soldiers. So if the Security Council decides that military action must be taken, it must rely on U.N. members to volunteer their armies.This is what happened in 1950. In that year, Communist North Korea attacked South Korea. South Korea then asked the Security Council for help. The Council voted to authorize U.N. members to send military aid to South Korea. The U.S. and fifteen other countries agreed to send soldiers to help South Korea. These soldiers became a U.N. force that saved South Korea from conquest.
