Question is how much "all hell" really differs from the current situation?
Have people not learnt from the last 3 years of war in Ukraine that NATO doesn't have endless supplies? Or people still believe it's political decisions preventing Ukraine from receiving more, rather than physical limits to munitions for a 365 days/year war?
Is there any reason to believe the maximum sustainable level for NATO air operations hasn't already been achieved by Israels airforce and associated actions over the last 2 years in Gaza, Lebanon, etc?
While that leaves some assets untapped, like heavy bombers and the Navy, this should be a fairly limited volume.
Iran has the chance to break the illusion of NATO omnipotence once and for all. The alternative is probably to receive just as much punishment from Israel and "limited" US raids; but also letting NATO pretend it's holding back in its war of aggression.
