"The Iranian move is deliberately designed to rattle U.S. President Barack Obama. He has shown a decision-making style that assumes that he is not under time pressure to make decisions. It is not clear to anyone what his decision-making style in a crisis will look like. Though not a prime consideration from the Iranian point of view, putting Obama in a position where he is psychologically unprepared for decisions in the timeframe they need to be made in is certainly an added benefit. Iran, of course, doesn’t know how effectively he might respond, but his approach to Afghanistan gives them another incentive to act sooner than later."
This is a pretty interesting quote.

They think they can get inside the OODA loop.
Obama probably has never heard of it.
