Most arms manufacturing and exporting countries will happily jump on the bandwagon when a real -life war breaks out , regardless of any trade or political affiliations , or indeed not , with the participants. Britain's great chums , the French , happily supplied Exocet missiles , and spare parts for the Super Etendard aircraft that launched them , to Argentina , whilst steadfastly refusing to supply Britain with information necessary for the implementation of suitable ECM with which to counteract them , with fatal consequences.
                      As to the original question posed in the thread title ;
          Margaret Thatcher and her husband , Denis , as the major shareholders in the Falkland Islands Company , obviously stood to make a considerable financial loss if the Argentinian invasion had been successful. Her fervent patriotic jingoism was , therefore , somewhat understandable and, in the light of subsequent revelations about the barbaric conduct and disgusting actions of the invading troops , fully justified . In my opinion.
