Yes, I have more experience in identifying #antisemitism . Particular since I have written two essays on antisemitism in German folklore, and can recognize some patterns.
I know that the Israeli government can and often is ruthless in pursuit of its goals - the current one particularly. And what they are doing in the Gaza strip is evil.
But given their motivations, I can follow the train of thought of their decision-making processes. I can _not_ do that for your claims about "the Samson project".
Yes, Israel likely has Second Strike capabilities - i.e. the ability to fire off nukes even if much of Israel itself falls or is destroyed. This has been a standard part of #MAD doctrine for both the USA and the Soviet Union (now Russia), and the logic is the same here.
But I don't see the logical jump from Second Strike capabilities to "Israel has hidden a bunch of nukes in friendly or neutral nations in order to blackmail them / take them out in case Israel itself should fall".
On the practical side #NuclearWeapons are complex devices that have to be actively maintained. Hiding even one of them in foreign territory and maintaining it is a complex operation for any stretch of time - but doing that in _multiple_ nations, all of which have their own intelligence agencies who will likely try to keep track of the coming and going of (presumably) #Mossad agents? How are they going to pull of that?
On the political side, what is the cost-benefit ratio for such an operation? Many of these nations are _allies_ - why should Israel risk a massive political fallout if one of these nukes gets discovered? And the risk becomes bigger with every of these devices planted. Also, nukes are _expensive_ to build and maintain - why should they use their limited stockpile to hide them in friendly or neutral nations when they have so many enemy nations?`
No, all of this reminds me too much of classical antisemitic slanders, such as blood libel, host desecration, well poisoning and so forth where Jews are portrayed as an inherently malicious people.
And there are _much_ more rational and logical explanations why governments in Europe and North America support Israel. We _really_ need not - and should not - to unsupported conspiracy fantasies like this one.
