The March 11 Massacre of the 17 Afghan citizens, including at least nine children and four women, raises many fundamental issues about the nature of a colonial war, the practices of a colonial army engaged in a prolonged (eleven-year) occupation and the character of an imperial state as it commits war crimes and increasingly relies on arbitrary dictatorial measures to secure public compliance and suppress dissent.After the cold-blooded murder of the 17 Afghan villagers in Kandahar Province the US military and the ever-complicit Obama regime constructed an elaborate cover-up, exposing the Administration to charges of conspiracy to suppress the essential facts, falsify data and obstruct justice. All are grounds for criminal prosecution and impeachment.This massacre is just one of several hundred committed by US armed forces, according to the Afghan president, Hamid Karzai. It could ruin the Obama presidency, by putting him on trial for conspiracy to obstruct justice and arguably send him to jail for war crimes.
