By default, given the president’s predilections, the agreement struck between Iran, Barack Obama and the Democrat Party must be called an executive agreement.
Here’s why:
As specified by the Constitution, there are two types of treaties. The first kind has “received the advice and consent of two-thirds of the Senate and has been ratified by the President.” The second is “called an executive agreement,” because it rests on the president’s “authority to create international agreements with other nations without Senate approval.”
I think it’s safe to say that of the protocols afforded him by the Constitution, Obama will opt for the executive option in finalizing the deal with Iran.
Obama’s Choice is to do executive override.
