They know their place
Iran can't go to war with Israel, it can't stand a chance, even with limited US involvement, Iran already is involved in 4 States, it resourced is stretched thin.Israel is like the little brat that kicks Iran in the leg, knowing full well it can be defeated while taking advantage that a retaliation towards the childlike state would entail a WW3, hiding behind the USA. So, this is not a fair symmetry. Iranians are not intimidated by Israel, but they will not start a war because they would have to fight the West, who we know would instantly back that damned country.
Israel would never send any missiles if it had no backing from the US + West. It is a country that deals with very conservative safety measures. All the bombardments and assassinations are within its safe zone extended by the guaranteed protection of the US. Israel is not interested in war with Iran contrary to what many people who lack reason think because they would lose. America, contrary to what many think, will not see any success in invading Iran. The West Asian country has a mountainous plateau with economic resources and human capital that far surpasses any of the countries in the region, with Russia and China providing them resources since they can bear staying outside the sanction sphere of the US if they play their part.Iran can't go to war with Israel, it can't stand a chance, even with limited US involvement, Iran already is involved in 4 States, it resourced is stretched thin.
Israel and Iran are allies in the Iran-Iraq war Israel sold them $82 billion dollars worth of weapons they both have the same goal destroying Arab countries read on the trident agreement.
