Listen, GOP, we get it. The Iran deal could fail miserably. But what if it doesn't?
We have an opportunity to stop Iran, with diplomacy, from further pursuing a nuclear weapons program and bringing it one step closer to joining the community of nations. This does not cover all our gripes with the regime, but it is a big first step.
So why the GOP opposition? I imagine it's because it's not their horse leading the charge. Richard Nixon and Ronald Reagan both negotiated with the Soviet Union and signed deals with a mistrusted regime could have wiped America off the face of the Earth. Sure, we don't trust Iran, but it doesn't have the power to spill my Starbucks on a sunny morning - which means we are in a stronger negotiating position.
Change happens when "the people" get a little taste of capitalism, and some Starbucks. Perhaps easing sanctions on Iran and giving them a taste of the high life will cause some change there. If we can delay the regime from pursuing a bomb, maybe "the people" will decide it's time for change.
Heck, even Bill O'Reilly suggested giving peace a chance.
