My recollection is that his actions had two basic components. First, there was the public diplomacy component. Kennedy revealed the information we had about missile deployment in Cuba to the public.

The second component was the threat. Kennedy made some pretty tough threats.

Based on that one might suppose that Allison is suggesting that the Bush Administration should be forthcoming with whatever information it has at its disposal on Iranian nuclear weapons development. This won't be as effective as it might be because of the Administration's reputation for grooming intelligence (earned or not) and the relentless opposition of the press.

The other component would, presumably, be more explicit threats than the oblique statements that have been made to date.

And of course this is a very useful suggesstion, especially when you are in the smallest room of your house and no other paper is available.

As far as I can tell, this is the entirety of Allison's plan:

If Iran is to be prevented from building nuclear bombs without war, the US must now explore negotiating options that are unpalatable but nonetheless better than the options a President will face at the end of the road he is now on.

I agree as far as it goes. But that's not very far!

"If Iran is to be prevented from building nuclear bombs without war, the US must now explore negotiating options that are unpalatable but nonetheless better than the options a President will face at the end of the road he is now on."

I don't know in which planet Allison has been reading again his old book, but he should know that for the past several years the US has been exploring negotiating options jointly with EU governments.
