It's a little like what happened to England during the Revolutionary war here in the U.S. Basically, General Washington only had to not lose this war. He didn't have to win it.
Iran is in this exact same position where they ONLY have to not lose this war completely and right now this is exactly what they are doing.
The other thing is that U.S. Ground troops won't survive in Iran at all unless they are inside tanks and armored vehicles or in bunkers 24 hours a day now because of what I call "Hand Grenade Drones" especially with fiber optics which kill soldiers (especially Russian soldiers) in Ukraine at a rate of 30,000 to 35,000 a month now (all types not just fiber optic ones).
So, Americna troops would die like flies a little like Russian soldiers are now and at least 12 Israeli soldiers have also died from fiber optic drones that cannot be electrically jammed to stop this carnage.
The only defense soldiers have at present is netting around where they are to catch the drones or to be inside buildings and tanks and armored vehicles or in underground bunkers. But, even in buildings drones can fly through windows too so unless you have netting on every window soldiers can also die inside of buildings too because these drones can be flown inside of buildings if they break through the windows to begin with and the rotors still work.
The point is that if Iran sends a 20,000 dollar drone and the U.S. knocks it out of the sky with something that costs 1 to 4 million dollars this is not a winnable war.
You do see this right?
In the long run the U.S. and Israel will only be bankrupt during a war like this with Russia building 20,000 dollar drones and sending them into Iran every single day to use on all the countries around them including U.S. Ships and planes.
