In light of the current Govt's policies, I haven't been in an Israel-defending mood for a few years.
Of course, your string is based on a Preposterous Israel-bashing premise.
No one can be 'forced' to sign the NPT, and those in it are free to withdraw.
Iran/Ayatollah Iran, REaffirmed the Treaty in the 90s Knowing Full well Israel had Nukes and they didn't.
The are free to Withdraw from it.
So making it mandatory for Israel TO join is just a piece of selective
absurdity/hostility.
And when Israel developed Nukes it was (and still is) in a UNIQUE geostrategic situation. Literally, a few million surround by 50 times their number.
NO Country, including the USA or former USSR, Ever had a better justification for developing and possessing Nukes.
Now I see you Dragged up old Sabra and Shatilla.
Of course, that massacre was one of just SCORES of tit-for-tat massacres between Lebanese Christians and Muslims.
ie, the much LARGER but much LESS known 'Damour':
Damour massacre - Wikipedia, the free encyclopedia
Though I prefer the more gritty/GRAPHIC:
Lebanese Forces : Historical Fact: The Massacre and Destruction of Damour
But hey, there was a Jew in the neighborhood for this one so, what the Hell "War Crimes!", "Genocide!", "Attica!"
What next? USS Liberty?
