Please consider the consequences
Many Republicans seemed disturbingly eager to condemn the international agreement regarding Iran, some not even bothering to wait for the agreement to be reached before condemning it.
A few Republicans, such as presidential hopeful Mike Huckabee, ridicule the whole idea of negotiating a deal with the untrustworthy regime of Iran, regardless of the degree of verification that is mandated.
The agreement does not rely on trust. Violation of the terms enumerated in the document would automatically and immediately bring back the international sanctions that pressured Iran into the talks in the first place.
The negotiations included other nations besides the U.S. and Iran. The cooperation of other nations in the economic sanctions against Iran required a major effort by the Obama administration. The other participants in the sanctions are also participants in the agreement.
There is no question that if the U.S. backs out of the deal, the cooperation that made the sanctions effective will fall apart.
Without a diplomatic solution, there remains only a military option to impose our will on Iran, meaning war.
Those advocating that we head down that path should be certain that their opposition to the agreement is based on an objective evaluation of the document rather than simply hatred of Obama.
