“The big questions would be, How would Europeans and Iranians react? It’s hard to believe that the Iranians would stick to their end of the deal. That would leave Iran open to take their nuclear program as far as they want.
“The Europeans would probably try to keep their portion of the deal in place and try to salvage it. This would place the burden of having blown up the deal on us. This would be particularly ironic, considering that a major Republican and conservative talking point is that the Obama administration is breaking faith with our allies. We would be alienating and breaking faith with our European allies right out of the gate. You’d be irreparably damaging our transatlantic relationships for however long Scott Walker were in office.
“Putin is not going to leave power anytime soon, unless he keels over. For all the talk about the Russian threat, it would be odd to throw our European allies under the bus on Iran at the same time they are facing down a Russia that is not particularly friendly.
“There would be a lot of ripple effects around wherever the U.S. and Europe have security cooperation. This is a reckless, irresponsible, shoot first, don’t-ask-questions-ever approach. It’s just not a viable strategy if your goal is to keep Iran from getting a nuclear bomb.”
