Is that really what we're debating? We all know it isn't.
What's important is can they get away with it before losing the support of those propping them up.
When the US and their buddies bombed the fuck out of Iraq and Afghanistan, and we all gathered around to watch the display of "shock and awe" did we bother to find out what they were bombing? Or did we just just go "take that, Taliban and Al-Qaida"?
Anything Israel are doing has been done before by their allies. They know it's shady as fuck, but also know they got away with it too.
