We learned in recent months that the CIA had seen some of its local covert operatives rounded up in Lebanon following an apparent security breach caused by Hizbullah infiltration; las Friday Hizbullah's Al-Manar TV named some names, identifying at least 10 CIA agents oerating under diplomatic cover at the US Embassy. For the Al-Manar reports, see here; for secondary accounts, here and here and here.
One can assume that the Lebanese nationals whose cooperation was exposed are in deep trouble; the Americans under diplomatic cover whose cover was blown are professionally hampered. We may never know all the details, but it's certainly a setback. Even ads Iran is disassembling our stealthy remotely piloted vehicle, Hizbullah has disassembled CIA operations in Lebanon and had at least some of its tradecraft revealed.
I see nothng to be gained by restating the information already leaked; it's out there openly and there's little to add; those named are already gone. But in the shadowy world where such stuff takes place, the US has clearly suffered another setback..
