'Consistent with the letter and spirit of Geneva?'

"... Champions of new sanctions dismiss these concerns. “We consistently hear about how we have to worry about the hard-liners in Iran. And it seems that the Iranians get to play good cop-bad cop,” Sen. Menendez recently said, but “we can’t.” Menendez contends that new sanctions legislation “strengthens the administration’s hand” in negotiations by conveying to Iran “[t]his is what’s coming if you don’t strike a deal … . But if we strike a deal, those sanctions will never go into effect.”
But imagine if the situation were reversed.
Suppose the Majles, Iran’s legislature, passed legislation tomorrow, over Rouhani’s objections, declaring that Iran would resume and escalate its nuclear activities in six months’ time if Washington failed to live up to its Geneva commitments and agree to a final deal that fully respects Iran’s nuclear rights....
Suppose further that when asked by an Iranian reporter whether this legislation risked undercutting diplomacy, speaker of the Majles Ali Larijani pooh-poohed the notion, assuring the media that this in no way violates the terms agreed to in Geneva. After all, Larjani would say, “Iran is doing nothing now. We are simply creating a sword of Damocles as leverage to ensure the Americans live up to their end of the bargain and accept a final agreement that respects Iran’s red lines.”
How would U.S. lawmakers view such a move? Would they see it as consistent with the letter and spirit of Geneva?..."
