During the Falklands War, Argentina attacked and caused to be scuttled a neutral merchant vessel.

By June 8, 1982, after a stop in Brazil, the Hercules was in international waters about 600 nautical miles from Argentina and 500 miles from the Falklands; she was outside the "war zones" designated by Britain and Argentina. At 12:15 Greenwich mean time, the ship's master made a routine report by radio to Argentine officials, providing the ship's [488 U.S. 428, 432] name, international call sign, registry, position, course, speed, and voyage description. About 45 minutes later, an Argentine military aircraft began to circle the Hercules. The ship's master repeated his earlier message by radio to Argentine officials, who acknowledged receiving it. Six minutes later, without provocation, another Argentine military plane began to bomb the Hercules; the master immediately hoisted a white flag. A second bombing soon followed, and a third attack came about two hours later, when an Argentine jet struck the ship with an air-to-surface rocket. Disabled but not destroyed, the Hercules reversed course and sailed to Rio de Janeiro, the nearest safe port. At Rio de Janeiro, respondent United Carriers determined that the ship had suffered extensive deck and hull damage, and that an undetonated bomb remained lodged in her No. 2 tank. After an investigation by the Brazilian Navy, United Carriers decided that it would be too hazardous to remove the undetonated bomb, and on July 20, 1982, the Hercules was scuttled 250 miles off the Brazilian coast.
The ship was Liberian registered but what would have happened had that ship been a US or French flagged vessel?
