During the Falkland Islands War, Great Britain received significant international backing:

United States: Following unsuccessful mediation, the U.S. provided full support to Britain. This included supplying air-to-air missiles, communications equipment, aviation fuel, and other military stockpiles, as well as cooperating with military intelligence.1
European Powers: Most European nations voiced support for Great Britain, and European military advisers were withdrawn from Argentine bases.1

While most Latin American governments sympathized with Argentina, Chile was a notable exception, maintaining a state of alert against its neighbor due to a separate territorial dispute.1
