Hypothetically if iran has nuclear weapon to test or the ability to produce one quickly to test a test during this time wouldn’t be prudent because it would signal to certain countries to attack before they can miniaturize those nukes on top of missiles, a test right now would basically signal an act of war.
I do believe as I said before if Israel is taking their gloves off everyone else should to as I said numerous times Iranian forces have been hit numerous times in Syria it’s either react just as harsh as the Israelis or just pack up and start camp somewhere else.
