The United Nations, founded in 1945 to maintain global peace, faces increasing calls for structural reform after 80 years. Critics highlight its inability to act decisively due to the Security Council’s veto power held by five permanent members. Recent conflicts in Gaza, Ukraine, and missile exchanges in the Middle East have exposed the UN’s inefficiencies. Experts urge expanding Security Council membership, empowering the International Court of Justice, and reforming the International Atomic Energy Agency to restore the UN’s credibility and relevance.
