Large numbers of influential hawks in both parties were outspoken opponents of the P5+1 nuclear deal with Iran, and went on to try to destroy the deal in Congress, though President Obama ultimately vetoed the bills, keeping the deal intact.

Those opponents of the deal have been railing against it ever since, but with the election of President-elect Donald Trump, a number of them are now conceding that Trump should not attempt to "tear up" the deal, and should instead focus on enforcement.

One Trump adviser has already indicated that enforcement is the plan, though during the campaign Trump made conflicting statements on the matter. Either way, those who were desperate to stop the P5+1 deal seem to agree that it's not really practical.
