Because of this — and because the success of such a framework in avoiding an Iranian bomb requires rigorous inspections and verification of Tehran’s compliance — trust is important.

Anything that erodes trust is bad for getting lawmakers and voters on board with any Iran pact. This includes things that don’t have anything to do with Iran.

President Obama promised that under Obamacare, if you like your health plan or doctor you would be able to keep them. That promise turned out to be untrue. You don’t have to be a very clever wordsmith to argue Obama is saying to Iran, “If you like your nuclear program, you can keep your nuclear program.”

It’s a zinger even a Republican politician could deliver.
