After Argentina invaded the Falkland Islands in April 1982, Benn argued that the dispute should be settled by the United Nations and that the British Government should not send a task force to recapture the islands. The task force was sent, and following the Falklands War, they were back in British control by mid-June. In a debate in the Commons just after the Falklands were recaptured, Benn's demand for "a full analysis of the costs in life, equipment and money in this tragic and unnecessary war" was rejected by Margaret Thatcher, who stated that "he would not enjoy the freedom of speech that he put to such excellent use unless people had been prepared to fight for it".
