The State Dept says no worries:
Marie Harf, a State Department spokeswoman, said Wednesday that "our goal is to see forward momentum" by Saturday, not the full list. "We've never said it was a hard and fast deadline."
But the LA Times uncharitably harkens back a day or so:
Secretary of State John F. Kerry had described the date as the first of several "specific timelines" that would indicate whether Syria is committed to the deal that he and Russian Foreign Minister Sergei Lavrov had worked out.
"We agreed that Syria must submit within a week — not in 30 days, but in one week — a comprehensive listing," Kerry said Saturday. He said the U.S. would allow "no games, no room for avoidance, or anything less than full compliance."
Well, there are no games - they just aren't going to to do it.
The Wednesday State Dept press briefing is kind of amusing - the press wasn't buying the "not a missed deadline" idea, but the State Dept wasn't selling anything else.
