Is Iran an honest broker?  If you can't emphatically say that they are then this is moot.  

 

As far as the deal itself, just think about it.  What enforcement mechanism is there?  the IAEA can request an inspection (That the supreme leader of Iran has vowed to oppose) and iran has just under a month to respond...  It's not like you can move shutdown or alter illegal activity in a month or anything.  

 

And what if they give the inspectors the middle finger?   Snap Back sanctions?  Economic sanctions take time to be crafted put into place and have a desired effect (which is why you shouldn't through them away at the apex of their efficacy but that's a little trite at this point!)  

 

When you negotiate purely from the position that you want to avoid armed conflict at all costs then you're sunk.  Diplomacy is strongest when your military willingness and capability are strongest, not when you are in the middle of a military contraction and our Marines are now asking foreign governments for rides around the world.  

 

The saddest part about this whole thing is that if you step back and take a look at the entirety of the obama foreign policy projection, if everything is implimented in this deal and Iran is 100% compliant and somehow knocks ISIS back into the stone age then you are essentially going to be dealing with a terrorist superstate of IRAN, a further indebted Syria, and whatever parts of IRAQ (or the whole thing) that they choose to annex, that will have ready access to the tools and technology for the full proliferation of nuclear weapons.  

 

If you like your terrorism...  you can keep your terrorism!
