Like most of Washington, I was under the impression that the nuclear negotiations with Iran ended in July. There was the press conference in Vienna, the U.N. resolution that lifted the sanctions on Iran and the fight in Congress that followed. That turns out to have been wrong.
I should have been more suspicious when no one actually had to sign anything at the end of the negotiations or when the "deal" was not submitted to the Senate as a treaty for ratification. And while it's true that the Iranians have disposed of nuclear material, modified sites and allowed more monitoring, they also keep haggling over the terms.
Now, according to an Associated Press report, the Obama administration is considering a rule change to allow some Iranian businesses to use offshore financial institutions to access U.S. dollars in currency trades.
