Let's look at these statements:
“The United States had absolutely nothing to do with this,” said Tommy Vietor, a spokesman for the National Security Council. Secretary of State Hillary Rodham Clinton appeared to expand the denial beyond Wednesday’s killing, “categorically” denying “any United States involvement in any kind of act of violence inside Iran.”
“We believe that there has to be an understanding between Iran, its neighbors and the international community that finds a way forward for it to end its provocative behavior, end its search for nuclear weapons and rejoin the international community,” Mrs. Clinton said.
Based on Hillary's remark above - almost a plea for forgiveness - the New York Times gives an analysis that is likely spot-on:
The statements by the United States appeared to reflect serious concern about the growing number of lethal attacks, which some experts believe could backfire by undercutting future negotiations and prompting Iran to redouble what the West suspects is a quest for a nuclear capacity.
Looks like the Obama Administration is going the old appeasement route - let Iran continue with their bad behavior, and don't get them angry, or else they may use it as an excuse not to sit down with us in the future and talk about....where to sit at the next meeting.
Don't rule out the president's narcissism, either. He based his entire campaign on being the guy who could get quarreling groups together by the majesty of his words and the force of his will; to use force of another kind is to admit personal failings and defeat. And if Barack Obama is one thing, it is extremely, almost pathologically, non-self-reflecting...
But is it just all a feint; is the US actually complicit here? The harsh denials could be a cover, and a good excuse for the administration's myriad of anti-semites to embarrass and bash Israel (the only other suspect) under the guise of protecting it.
I doubt it. If that were there case, the Israeli denial-style would have been the way to go:
The Israeli military spokesman, Brig. Gen. Yoav Mordechai, writing on Facebook about the attack, said, “I don’t know who took revenge on the Iranian scientist, but I am definitely not shedding a tear,” Israeli news media reported.
Hey Barack - meet a real man...
Too gutsy for our American president, apparently, whether we are involved or not. Sure, the Iranian president is laughing up a storm, denying the Holocaust while building a nuke while making clear that boy-oh-boy, if you want to see a real holocaust, just give me another eighteen months! But that doesn't matter. Barack Hussein Obama has his feelings to worry about....and Hillary Clinton has a process she's ideologically compelled to follow.
And if another six million Jews should die? Well, as long as it happens after the 2012 elections...
