Hope or no hope, truth is becoming harder to come by. During the Vietnam war when Daniel Ellsberg leaked the Pentagon Papers, the New York Times published them. However, during the Iraq war when a National Security Agency whistleblower leaked the information to the New York Times that the Bush regime was spying on Americans without obtaining warrants from the FISA court as required by law, the New York Times told the White House and sat on the story for one full year until Bush was reelected. The newspaper might even have turned in the whistleblower. When the Guardian and other newspapers were threatened by the US government, they turned on Julian Assange and WikiLeaks, the suppliers of their headline stories.
To see the fate of whistleblowers, read Sibel Edmonds’ book, Classified Woman. Few people are willing to undergo such wear and tear in an effort to get truth to the American people.
There is another constraint on revealing truth. The human capital of people with inside knowledge is destroyed if they speak out. Position, contacts, invitations, income, and social life are all forfeited when an insider becomes a dissenter or a truth-teller.
