That’s your own (rather immature & uninformed) analysis. If Israel’s past track record is any indication, it would launch unilateral military strikes against against any site in Iran that was even remotely suspicious for weapons development.
Back in the early 1980’s, Iraq was constructing a nuclear reactor that it had purchased from the French. The reactor had been approved by the IAEA; and was both according to the French and most independent researchers, specifically designed to be unsuitable for weapon development. Israel felt otherwise, and unilaterally bombed the site, if I’m not mistaken, killing French civilians in the process. Although its actions were universally condemned by the UN and the international community, in the end they didn’t even get a slap on the wrist. No sanctions were initiated…this despite the fact that Iraq was still an important Western ally at the time, and European scientists were killed in the attack.
When Israel repeated the same stunt almost 30 years later in Syria, which hadn’t opened its alleged nuclear facilities to international inspection (unlike Iraq), and which was (and continues to be) a political pariah in the Western world, the international reaction ranged from open support in the West, to complete silence (and tacit approval) in the Arab and Muslim world. If Israel were to launch similar attacks against Iran (which they undoubtedly if the situation arose), I suspect the international reaction would be similar.
