Without whistleblowers, the mainline media outlets are more transfixed than ever with telling the official story. And at a time like this, the official story is all about spinning for war on Syria.

Every president who wants to launch another war can’t abide whistleblowers. They might interfere with the careful omissions, distortions and outright lies of war propaganda, which requires that truth be held in a kind of preventative detention.

By mid-week, media adrenalin was at fever pitch as news reports cited high-level sources explaining when the U.S. missile attacks on Syria were likely to begin, how long they might last, what their goals would be. But what about other (potential) sources who have documents and other information that contradict the official story?

It’s never easy for whistleblowers to take the risk of exposing secret realities. At times like these, it’s especially difficult -- and especially vital -- for whistleblowers to take the chance.

When independent journalist I.F. Stone said “All governments lie and nothing they say should be believed,” he was warning against the automatic acceptance of any government claim. That warning becomes most crucial when a launch of war is imminent. That’s when, more than ever, we need whistleblowers who can leak information that refutes the official line.

There has been a pernicious method to the madness of the Obama administration’s double-barreled assault on whistleblowers and journalism. Committed to a state of ongoing war, Obama has overseen more prosecutions of whistleblowers than all other presidents combined -- while also subjecting journalists to ramped-up surveillance and threats, whether grabbing the call records of 20 telephone lines of The Associated Press or pushing to imprison New York Times reporter James Risen for not revealing a source.

The vengeful treatment of Bradley (now Chelsea) Manning, the all-out effort to grab Edward Snowden and less-publicized prosecutions such as the vendetta against NSA whistleblower Thomas Drake are all part of a government strategy that aims to shut down unauthorized pipelines of information to journalists -- and therefore to the public. When secret information is blocked, what’s left is the official story, pulling out all the stops for war.
