I saw this headline and read the story in the NY Times and was pretty surprised.
The most major part of the story, I believe, was the decryption of the Soviet cables from New York to Moscow, which is only a minor footnote in this piece on the second page. That, coupled with the testimony of ex-KGB agents who have spoken frankly about the Rosenbergs' case since the fall of the former Soviet Union (and are somehow not mentioned in this article), long settled the twin issues of whether the Rosenbergs were really involved in espionage and how the U.S. government knew what it did.
It's never been entirely clear to me, though, where Ethel figured in (and the Greenglass testimony supports the idea of Julius but not Ethel being the real link to the Russkies).
The Mort Sobell confession only echoes what is already common knowledge, though somehow it seals the deal for the Rosenbergs' kids.
I'm against the death penalty so it doesn't matter whether you're Jeffrey Dahmer, Mumia Abu-Jamal, Julius Rosenberg, or Karla Faye Tucker -- I don't think the government ought to decide whether, or how, you will die.
That's one of the only truly unshakable beliefs I have, even if it puts me in a distinct minority of Americans (and even, amazingly, if it puts me in a minority among American Christians).
That fact alone gives me common cause with those who support certain causes celebres, but that's where I'll draw the line -- I definitely don't see anything 'cool' or 'heroic' about selling sensitive secrets to evil regimes or murdering police officers in Philadelphia.
