Nukes yes. Precision guided munitions with a very exact specific target, NO! The precision needed for this would entail a man on the ground or in the air to laser the target. To know what to laser would not come via radio communications even if encrypted. The only exception to this would be a known target with GPS coordinates. Even as such I would not think Israel would just send up pilots and call them on the radio and say, "just hop over to Syria and take this GPS coordinate off the face of the earth." I am not buying it. I still think the Washinton Post pulled this out of their butts.
The IAF has some home grown Precision Guided Munitions.

Sounds like Optical scene matching with a GPS back-up. It is conceivable that the bombs were pre-programmed, and the in-flight instructions just guided the IAF jets to the correct drop point.
