Why should anyone care about the secret diplomatic cables WikiLeaks has disclosed? So what if US State Department bureaucrats say unflattering things about other world leaders? Some people may be asking those questions in response to WikiLeakss latest disclosures. Okay, they say, leaks about atrocities on the battlefield (such as the first WikiLeaks disclosure, the Collateral Murder video) tell us something we should know about - the gross misconduct by US military forces, condoned by the command all the way up to the president of the US. But diplomatic cables? Who cares? We all should care. The documents serve as a timely reminder that the people who collectively call themselves the government are professional liars. Lying is what they are paid to do. They lie to their foreign counterparts, but mainly they lie to us. The biggest lie of all is that they do it in the American peoples interest. When American (mis)leaders profess confidence in the Afghan president and his government, while saying privately they are incompetent and corrupt - stealing hundreds of millions of Americans dollars - thats the American peoples business - at least as long as they are compelled to bankroll the US governments lethal operations. When American (mis)leaders praise and encourage the Mexican governments efforts in the criminal war on drugs, while privately believing theyre practically worthless, thats the American peoples business - at least as long as they are compelled to bankroll that evil crusade, which harms Mexicans and Americans. When American (mis)leaders bomb Yemen while conspiring with the Yemeni dictator to portray the murderous campaign as the act of Yemens government in order to make it more palatable to the Yemeni people, thats the American peoples business - at least as long as they are compelled to bankroll that dishonest and imperialist policy. When Israeli officials implore American (mis)leaders to bomb Iran and even to effect regime change to stop its unproved nuclear weapons programme, threatening to do it themselves if the US government wont, thats the American peoples business - at least as long as they are compelled to bankroll militarism and suffer the blowback such an action would produce. When Israel advises American (mis)leaders that a shipment of bunker-busting bombs should be handled quietly to avoid allegations that the US government was helping Israel prepare for a strike against Iran, thats the American peoples business - at least as long as they are forced to underwrite Israels aggressive foreign policy, which will surely harm Americans. When US Secretary of State Hillary Clinton orders diplomats to engage in spying and identity theft, violating among other things the countrys UN obligations not to do such things, thats the American peoples business - at least as long as the US government forces Americans to support the UN as vital to world peace, while using it to justify invasions, occupations, and the economic warfare of sanctions. Sure, at some level the American people already know that their (mis)leaders and (mis)representatives are chronic, systematic liars. Everyone laughs at the riddle asking how you know when a politician is lying: His lips are moving. But that knowledge too often fades deep into the background as the people are distracted or put to sleep by the solemn mendacity that issues from the politicians mouths on a daily basis. So WikiLeaks performs a critical service in exposing the underworld in which the real US government exists and operates. As the Economist, although a defender of secrecy, said, it is also inevitable that the prerogative of secrecy will be used to hide the misdeeds of the permanent state and its privileged agents. Some will say that this government - keeper of the empire, policeman of the world - could not exist without duplicity. I take them at their word. It again demonstrates that an imperial foreign policy conflicts with values Americans claim to cherish.
