A lot about the attack has been scrubbed. I picked this up the night of the attack, early in the morning on the 13th:

USA Ambassador John Stevens appears linked to enlisting and providing thousands of Libyan Al Qaeda fighters to assemble in the USA/NATO terrorist base in Turkey just across from the Syrian border, then having Turkish, French, Israeli, CIA and SAS commando's sneak those Libyan Al Qaeda terrorists into Syria.

USA Ambassador John Stevens died screaming from being burned alive, locked in the USA Ambassy saferoom when the surgical strike team torched the exterior. Many feel Amb. Stevens got what he deserved in a karmic blow-back and only the Creator knows if Stevens is still burning and screaming long after his body has been mostly recovered.

I expect the numbers of Libyan Al Qaeda 'showing up' in Syria to drop dramatically now.

This following the assassination of the Saudi Prince appears to be the 2nd very high level targetted, precise assassinations on those directly linked to pouring Al Qaeda from Saudi Arabia and now from Libya into Syria. Therefore this latest surgical strike is a huge defeat of the Satanically evil Zionists leading Apartheid Israel's agenda in destroying Syria on their goose stepping march to do the same with Iran.

(My comment: It wasn't too much of a setback considering what has transpired in Syria since the attack. ISIS on the move.)
