The victors write history and they do this to ensure only their version of history will be known. It used to be decades or sometimes centuries before the truth about an event came out.
In the meantime, what develops are two narratives. One is what the newsmedia, the powers that be sell us-John F Kennedy was killed by a lone gunman, the Oklahoma City Bombing was committed by two men, Israel didn’t ethnically cleanse Palestinians when they declared a state, The US didn’t openly recruit ex-Nazis during the Cold War and didn’t overthrow democratically elected government or damp down democracy and install right wing dictatorships.
The other narrative is what burbles beneath the surface. The evidence shows something and the government and corporate news media tells us something else.
The Internet has now given us more information than we know what to do with. It has given us in some cases different versions of the truth. It is now impossible for these huge cover-ups to happen although the world doesn’t necessarily do anything with this information.
What does Wiki Leaks have to do with this? The jury is still out on the effectiveness of this organization. For one, it is still not known what effect they had on the coup in Tunisia a couple of days ago.
