The hostility between Iran and Israel has always been more talk for domestic political goals than any real danger of war between the two. Iran sees Israel as a useful boogieman to be against that Iranians can get behind and Israel sees Iran’s supposed nuclear threat as a useful scare tactic to win elections.
Benjamin Netanyahu is very much like Trump in that he thinks more about staying in power by any means (lying or whatever it takes) and knows full well that even if Iran did have a nuclear weapon it would never be used against Israel. First the two countries are separated by several countries between them and second Israel has nuclear weapons and the USA is an ally so attacking Israel would be fool hardy to say the least. Besides, any nuclear explosion in Israel would kill many Muslims as well. On top of that, nuclear weapons have proved to be war preventers NOT war starters – AS LONG AS BOTH SIDES HAVE THEM.
Israel’s latest moves against Iran’s nuclear program are an effort by Netanyahu to keep the scare alive and help him maintain support even from those Israelis who do not like him. It is also aimed at making things tougher for President Biden in his bid to rejoin the Iran nuclear agreement. Netanyahu NEEDS Iran as a scare tactic and a deal between Iran and the US hurts that need.
