Iran Talks Resume After Late-Night Session

Negotiators were still meeting Thursday, blowing past Tuesday’s self-imposed deadline for a broad agreement on how to deal with Iran’s nuclear program. Neither Tehran nor the United States and its allies want to blink first, and neither side wants to be the first to leave the table. And both sides want to be very clear: If there’s a stalemate, it’s the other side’s fault. They’re not just trying to avoid political embarrassment at home. For both the United States and Iran, a perception that they caused the breakdown could put them in a worse position on the world stage than they were in before the talks started 18 months ago.
