That POS is apparently still alive. I saw some of his videos. In many he repeats the "We don't need the US", Jews can manufacture everything, Jewish minds invented everything, etc.. in a recent one though he went into "if you don't keep sending supplies we will use nuclear weapons."

He has been advocating for the use of nuclear weapons and an EMP on the south of Lebanon.
I think the big secret surrounding Israel's nuclear arsenal is that it pretty much doesn't exist.
There used to be a trope in old 70's TV shows where a guy would threaten a dude with a bulge in his jacket pocket that concealed a revolver. Of course, you don't actually need a revolver if the other guy assumes you have one.
I believe that's what we have here. If you look around, there are a handful of analysts that suspect the same thing. When you carefully search for the specific concrete evidence of the arsenal, you find it's a mirage.
That being said, it's a long and untold story but they stole about 50 devices of 5kT each (from the US, of course) at the beginning of 2019. One of them was used on Port Said. They also appear to have discreetly used a few of them in the current war.
But the thing is, why would you need to steal a few very small nukes if you supposedly had a bunch of big ones at your disposal, and the capability of manufacturing any more that you need? It strongly implies the opposite.
Very plausible, I think even Jewish Americans wouldn't trust Jewish Israelis with a nuclear arsenal. Not because they care about humanity but for the Jewish Israelis own sake.
Giving Israelis nukes is the equivalent of giving your 5 year old son a real gun.
