Story : Until now, the three-man Argentine junta which led the invasion of the Falkland Islands has kept its secrets. Tonight, for the first time, a junta member, Air Force General Basilio Lami Dozo, speaks out. His Exocet missiles were the most deadly threat to the British Task Force. And an in-depth look at the US Secretary of State Alexander Haig's attempt to avert a war - and save his own job. He promised President Reagan, "We'll walk this kitty back". Shuttling between General Galtieri and Margaret Thatcher - who dubbed him "Woolly AI" - Haig's moments of elation and disappointment, revealed here for the first time, became increasingly desperate as the Task Force steamed steadily southwards - to war.
