You need some spectacularly good shielding in that case.
The US has dropped Rangers and then a NEST team onto a ship in the middle of the Atlantic before. Apparently detected fissionables from orbit.
Considering how long Israel chased after SS officers, even just guards at one of the camps, well, I'd personally put the odds of anyone surviving the retribution for nuking Israel at zero. Them, their family, probably even their entire extended clan. Because they extinguished the extended clans of those doing the retribution.
And hell, the Egyptians would probably help.
