I suggested one reason: top GOP donors like Boeing stood to cash in big-time if the Iran deal was consummated. Boeing had ingratiated itself with Tehran when Obama granted some sanctions relief for Irans crippled aviation sector in order to keep the mullahs at the negotiation table. Boeing leapt in to provide Iran Air, the regimes national carrier, with all manner of assistance notwithstanding that Iran Air, basically an arm of Irans Revolutionary Guards Corps, was best known for providing material support to Hezbollah and the Assad regime. Indeed, in 2011, the Treasury Department designated Iran Air as a proliferator of weapons of mass destruction. By helping Iran at a key point in the negotiations, I pointed out, Boeing stood to win huge Iranian contracts once the Iran deal was approved and sanctions were lifted.

This is crony capitalism at its worst. It's also why so many of the "neo-cons" who polluted the Bush administration and pushed that stupid war in Iraq are supporting Hillary Clinton.
