Tony Blair's new socialist government is obviously more concerned with ideological revenge than diplomatic convention. During the Falklands War, Gen Pinochet aided Britain, and saved many British lives, even allowing Britain's SAS commandos to operate against Argentina from Chile. So much for British gratitude. In 1973, army commander Pinochet overthrew Marxist Salvador Allende, who was turning Chile onto a Stalinist state. Pinochet, backed by the US and Britain, led the subsequent war against marxist terrorists.
All urban wars are dirty and bloody.
Look at Northern Ireland, Israel's war against Palestinians, or Algeria. Marxist urban rebels tried to overthrow Chile's government, using bombings, assassinations, kidnapping and guerrilla assaults. Chilean and Argentine security forces were ordered to fight an all-out war against the communist rebels. Terror against terror. In the process, some innocent people were arrested, tortured or disappeared.
