Diplomacy is always the superior alternative to brinksmanship. While I understand that Republican lawmakers would like to have the ability to negotiate foreign policy taken away from the Executive Branch of the Federal Government in the present circumstance, due to the opposing party holding the office, there is no sensible way for them to negotiate foreign policy on this, or any topic. My senator, Ron Johnson, is a local business man with few, if any, qualifications that would make him an expert in either Middle Eastern diplomacy nor in nuclear proliferation. His continued insurance that Congress should reject what is essentially a hard negotiated peace agreement is akin to treason. The deal should stand, and the brinksmanship should stop.
