IT IS HARD

To compare the Iran Deal with the Treaty of Versailles.

I do not know the behind the scenes discussions that have been under way, but certainly there has not been a major world war as an antecedent to the deal.

Further, the US role, diplomatically, at either time, was not  as great as Americans have been long trained, including by those such as Professor Kaiser, to believe.

Militarily, the nuclear umbrella is a faux, I call it a Mary Poppins, umbrella. 

Conventional forces are a faux threat, absent dire need.

Drones only "work" in places, frankly, where you do not really care about collateral damage.

If you use drones there, 
you do not care, at all, about the population there, really, frankly. 

Period. You can kid yourself.
