When asked about what he thought about Vladimir Putin's piece being published in the New York Times, McCain said he hoped that HE would able to publish something in Pravda.
First of all, Pravda is the paper of the Russian Communist Party. Putin's party is Russia United.
Second, Pravda ceased publication for several years and then came back in a much more modest form. It's not a mass circulation paper.
Third, Putin is the PRESIDENT of Russia. How would John McCain publishing something in a Russian newspaper be equivalent to Putin publishing something in the New York Times?
During the Soviet era, it was fairly common for Pravda to publish letters to the editor from the U.S. At the University of Oregon, a member of the College Republicans was bragging about he got a letter to the editor published in Pravda.
There was a Cuban psychologist who interviewed McCain in Vietnam. According to an article on Counterpunch.com http://www.counterpunch.org/2008/06/13/mcnasty/ :
According to Fernando Barral, a Cuban psychologist who questioned McCain in January 1970, “McCain was "boastful" during their interview and "without remorse" for any civilian deaths that occurred "when he bombed Hanoi." McCain has a similar recollection, writing in his [autobiography] that he responded, "No, I do not" when Barral asked if he felt remorse.” (9)
McCain told [Barral] that he had not been subjected to “physical or moral violence,” and “lamented in the interview that ‘if I hadn’t been shot down, I would have become an admiral at a younger age than my father.’”
“Barral said McCain boasted that he was the best pilot in the Navy and that he wanted to be an astronaut.” The Cuban psychologist concluded that McCain was [a] ‘psychopath.’” (10)
