There should be no worries. Isreal has nothing to lose, and everything to gain by eliminating the threat. This also takes the pressure off of the US (I assume we already have our bombing raid laid out and ready to execute if it comes to that). We will, of course, be scolded by Russia, France and China for supporting Isreal in it's tactical plan. Hell, we most likely already gave Isreal the hardware required to penetrate the facilities (Which if I remember correctly, are fortified and deep underground).
the option described is better than the "Sampson
Option" being initiated.
Here in the last several months it was reported that the U.S. sold many bunker buster bombs to Israel. I am not sure but I think they are filled with depleted uranium and go through steel and concrete like a hot knife through butter.
