It wasn't only Obama who has flip-flopped on his red lines on lifting sanctions on Iran.
Here's Hillary Clinton writing in 2007:
As a result, we have lost precious time. Iran must conform to its nonproliferation obligations and must not be permitted to build or acquire nuclear weapons. If Iran does not comply with its own commitments and the will of the international community, all options must remain on the table.While Hillary has been mostly silent on the current Iranian negotiations, if she still held by these opinions one would expect that the Democratic frontrunner for president would have spoken up.
On the other hand, if Iran is in fact willing to end its nuclear weapons program, renounce sponsorship of terrorism, support Middle East peace, and play a constructive role in stabilizing Iraq, the United States should be prepared to offer Iran acarefully calibrated package of incentives. This will let the Iranian people know that our quarrel is not with them but with their government and show the world that the United States is prepared to pursue every diplomatic option.
