Many people compare Edward Snowden to me unfavorably for leaving the country and seeking asylum, rather than facing trial as I did. I don’t agree. The country I stayed in was a different America, a long time ago.

After the New York Times had been enjoined from publishing the Pentagon Papers — on June 15, 1971, the first prior restraint on a newspaper in U.S. history — and I had given another copy to The Post (which would also be enjoined), I went underground with my wife, Patricia, for 13 days. My purpose (quite like Snowden’s in flying to Hong Kong) was to elude surveillance while I was arranging — with the crucial help of a number of others, still unknown to the FBI — to distribute the Pentagon Papers sequentially to 17 other newspapers, in the face of two more injunctions. The last three days of that period was in defiance of an arrest order: I was, like Snowden now, a “fugitive from justice.”

There is no chance that experience could be reproduced today, let alone that a trial could be terminated by the revelation of White House actions against a defendant that were clearly criminal in Richard Nixon’s era — and figured in his resignation in the face of impeachment — but are today all regarded as legal (including an attempt to “incapacitate me totally”).

I hope Snowden’s revelations will spark a movement to rescue our democracy, but he could not be part of that movement had he stayed here. There is zero chance that he would be allowed out on bail if he returned now and close to no chance that, had he not left the country, he would have been granted bail. Instead, he would be in a prison cell like Bradley Manning, incommunicado.

He would almost certainly be confined in total isolation, even longer than the more than eight months Manning suffered during his three years of imprisonment before his trial began recently. The United Nations Special Rapporteur for Torture described Manning’s conditions as “cruel, inhuman and degrading.” (That realistic prospect, by itself, is grounds for most countries granting Snowden asylum, if they could withstand bullying and bribery from the United States.)

Snowden believes that he has done nothing wrong. I agree wholeheartedly. More than 40 years after my unauthorized disclosure of the Pentagon Papers, such leaks remain the lifeblood of a free press and our republic. One lesson of the Pentagon Papers and Snowden’s leaks is simple: secrecy corrupts, just as power corrupts.
