You write: "if diplomacy fails." But, if you ask me, diplomacy has only gotten us jerked around by the Iranians. It has failed for quite some time now.
I think the US is no match for the Iranians in negotiations. We will be toyed with until it is too late. Another nation would have acted already.
The US will ponder and consider and then finally decide on some military action AFTER Iran has developed a nuclear weapon. And, when we finally decide to act, the public will come down hard on the Administration and undermine the government in the world media. I wish I could say that I was optimistic that diplomacy will yield something other than further delays and billions in corrupt payoffs, giving the Iranians the time they need to build the weapons and secure their assets.
I am not optimistic. Sadly, the US lacks the military power to decisively take on the Iranians. Equally sadly, other than one ally which always needs to sit out publicly with regard to initiatives in the Middle East, ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
