I posted this comment today to Dafydd ab Hugh, of Big Lizards Blog
Your analysis, as always, is impeccable, and I would know if it was peccable, because I read all the Left's columnists too.
Simply, Israel must attack Iran. If Israel waits, Iran becomes stronger and the inevitable future war more costly. The fallacy of warfare which has entrapped the West is that you only fight to your opponent's capabilities. A fair fight may excite boxing fans, but the survival of a nation is not sport.
When Israel attacks Iran, we had better be ready to defend from terrorist attacks and attack Iran ourselves. Another fallacy of our times is that a sovereign nation cannot be attacked if it harbors terrorists but doesn't overtly use its own forces. The stupidity of allowing terrorists sanctuary didn't make sense even when North Vietnam had the USSR and China as protectors, and it makes no sense at all now that those two powers are not players.
George Bush the Elder listened to all the smart guys and outsmarted himself. Real politick was born of Cold War cynicism, perpetuating un-democratic states as a balance against the power of others. Nothing is solved, only the tensions are preserved to play havoc another day.
