GEORGE Fernandes is a man who believes attack is the best form of defence. In a blizzard of accusations, the defence minister has buried five specific grounds for sacking the chief of naval staff: that he repeatedly defied the authority of government; that he violated the Navy Act by trying to harm the career of his subordinates; that he lied to the government on matters where he should have kept it briefed; that he was mentally unbalanced, habitually flew into a rage and threatened junior officers; and, most serious, that he endangered national security by leaking information to two newspapers. Not one of these hold up under serious scrutiny.
