Below is a link to S2 Underground, and its very clear this guy was former S2 when he was in the Military. He has a weekly wrap up he posts on Saturday, and I have no doubt it will be VERY informative about the current situation in Iran.
FWIW, he posted an interesting hypothesis earlier this week about one "possible" reason the US was rushing forces into striking distance so quickly, to include one Carrier that was due to head home. According to him, the US "might" have intel that Israel was planning on a single nuke strike on a target, thus prompting our rush in this operation. Maybe true, maybe not, but we are in it now for good or ill.
