Israel (and the US) really do have a cheek saying that (unlike them) Iran can't have Nuclear deterrent weapons, when you consider Israel was formed under the threat of Truman's nuclear weapons, which at that time (1948) were not a deterrent as he (Truman) was the only one with them, they were a grave threat to humanity. Going by that fact alone let alone the previous fact (Japanese Cities), I would be more worried about a Nuclear armed America and Israel, than a nuclear armed Iran.
IMO it's a fact that Jewish president Truman threatened my Country with Nuclear annihilation (like with Japan) in 1948 if we did not cede control of Palestine. That in true Trump caps lock style is UNFORGIVABLE IMO!! Especially if you consider that America would never have defeated japan and Europe if we were on Germany's side. It was defeated and kidnapped German scientists that unlocked the Nuclear secrets, he (Truman) never developed them! Never trust people who stab you in the back!!!!!!!
America only stopped after other Countries (including UK) developed their own weapons as a deterrent. THAT is why I am sympathetic to Iran craving a deterrent while Israel and the US have these devastating weapons and a proven willingness to use and to threaten to use them.
