Cause and effect in MidEast nuclear arms race

Here's a letter which appeared in The Independent last week. I missed it at the time but caught it in The Week magazine:

So let me get this right. William Hague warns that Iran acquiring nuclear weapons would start a nuclear arms race in the Middle East. Where is the sense of history? Fifty years ago, John F Kennedy was firmly opposed to Israel acquiring nuclear weapons for precisely that reason. By that measure, hasn't the good Mr Hague got cause and effect interchanged?

Tbe Independent headed the letter, Blind to history whereas The Week headed it, Nuclear muddle. There's no reference to the original article or letter to which PH Ladbroke was responding. I'm guessing it was this from Feb 18.
