Can Iran win a war against Israel?

Israel can only win a total war against Iran if they get all support from countries like USA and UK. Iran is not able to get such support on mass level. There is no chance that Iran can win a war against Israel, because USA is the most powerful army in the world and together with Israel and UK they can win against every nation in the world. The only country which would be very hard against the 3 would be China, but other Western armies calculated the West can win against China and Russia if they fight a total war on the same time. Other countries mostly are not stron enough to attack USA and UK on their soils.
