The New York Times has an op-ed by one Alan J. Kuperman, who has a snazzy-sounding title at U. of Texas, Austin. He spends a chunk of time setting up his credentials as an expert, but then suddenly takes off in a belligerent direction: The only thing that will stop Iran from causing nuclear damage is to bomb it. By the US, not Israel, because it will need to be bombed repeatedly.
I don't say much on this matter, because I don't know enough about the many technical and cultural aspects to have anything meaningful to say. (Though I did once, in some detail, here). Nor do I know to tell how representative this Kuperman fellow is of anything. I doubt he has a hot-line to the White House. Still, Obama's outstretched hand has clearly found a clenched fist in Teheran, with sharp steel knuckles. Something will have to happen.
