Delusions.
US could have full control of Iranian airspace in a week if it went all out.
There simply isn’t the necessary systems in place to build reliable kill zones against F-22, F-35, and B-2. Against hundreds of planes eventually any system would collapse. Plus you add in Iran has so much mountainous terrain that causes dead zones for radar and enemies can exploit.
Iran also has no modern Air Force to patrol the borders blocking incursion attempts or meeting enemy squadrons over the Persian Gulf.
Again, you can’t expect much out of a country that spends $25B/year on military vs the strongest empire in modern history that spends $900B/year. The deterrence that prevented all this was Iran’s missile program and proxies would set the Middle East on fire and the Persian Gulf would be shut down, etc.
But it seems a lot of that deterrence was bluster and rhetoric. The missiles while deadly, required hundreds to be expended to break thru Western shields. The West used the war in Yemen and the hundreds of ballistic attacks the Houthis did to prepare against an eventual Iranian salvo.
Not sure what Iran’s plan is this time around.
