Using Israel's logic for attacking Iran (to protect itself from (non-existent) Iranian nuclear weapons), every country in the Middle East (and beyond) would be justified in attacking Israel and destroying its (still undeclared) arsenal of 90 nuclear warheads. Trump’s assertion that if Iran developed a nuclear weapon, it would automatically use it against Tel Aviv, is preposterous, since Iran doesn’t want to be annihilated and surely would be  if it did so. Israel, on the other hand, could nuke Iran and get away with it, as the US did Hiroshima and Nagasaki.
