This book constituting a review on the event of Falklands War in 1982, is trying to reveal the facts that the occurrence of such a war was caused by the political and military miscalculations. General Leopoldo Galtieri had a strategic assumption that he was so confident about, namely that the military force planned to seize Falklands would not make British mobilize its military power, but it would settle it down at the negotiation. And the quick response of British becomes the main factor determining its victory in Falklands.
