The documents appear to reflect our spying on Israel
*sigh*
Not a good move on the part of the US.
Afraid if I were the Iranian intel type who received this gift, I would be very very wary.
Who involved can Iran trust?
Between the lack of trust even citizens of US have in their government of late and the way Israel has been pulling coup after coup on everybody in sight ever since '48, it's entirely possible that 1) Israel leaked a bogus plan for the US pass along, 2) US intel made up the plan to paint Israel as aggressor, 3) Whatever plan got passed Israel has already changed it to trap/destroy Iranian counter moves.
...or any permutation or combination that you can imagine.
All things considered I'd vote to play a nice game of chess.
