Talks stretch into second day past deadline

The deadline came and went, now we're at deadline +1, heading into deadline +2.  Reuters: "The negotiations, aimed at blocking Iran's capacity to build a nuclear bomb in exchange for lifting sanctions, have become bogged down over crucial details of the accord, even as the broad outlines of an agreement have been reached . . . .
U.S. Secretary of State John Kerry and German Foreign Minister Frank-Walter Steinmeier said they would stay at least until Thursday in an effort to seal the "political" agreement, a milestone toward a final pact due by the end of June. In a potentially hopeful sign, French Foreign Secretary Laurent Fabius returned for more talks after flying back to Paris the previous day because progress had been too slow.  "We are a few meters from the finishing line, but it's always the last meters that are the most difficult. We will try and cross them," Fabius said upon his return . . . . The talks - the culmination of a 12-year process - have become hung up on the issues of Iran's nuclear centrifuge research, details on the lifting of U.N. sanctions and how they would be re-imposed if Iran breached the agreement."  As the WSJ reports, "[m]issing Tuesday’s deadline has no automatic consequences for the talks. The interim agreement reached in November 2013 remains in effect until the end of June."  Nonetheless states the Washington Post, "by blowing through self-imposed deadlines, Obama risks further antagonizing lawmakers in both parties who are poised to take their own action to upend a deal if they determine the president has been too conciliatory."
