You must be joking. Saudis are well trained in what? How fast they will run away from battlefield? We see Saudi capabilities in Yemen, where they are regularly beaten by Houties. Iran is experienced army. They figh eight years long war with Iraq in eighties. Also they give a lot of experiences to their troops in Iraq and Syria. Who stop ISIS in front of Bagdad? It was Iran Al Quds units under command of general Suleimani. Iraqi army was broken in that time and unable to fight. Iranian troops also got a lot of experiences in Syria and learn a lot about air defense with Syrians and Russians.
I was talking about USA.
Iranian experience against isis won't help against US air force and navy. Again they will just use their airforce and navy. No boots on the ground.
Air defense is quite different story. IRIADS is now independent branch of armed forces and Iran invest a lot in it. They produce old stuff like HAWK, but deaply modernized with digital electronics, new radar homing heads, etc and well improved comparing to original, similar as original S-125 Neva and modernized Pechora-2M. They are producing new domestic stuff and now they muster PESA and AESA radar technology. All their air defense complexes are now integrated in modern IADS, so their effectivenes is now far higher than before. You could see now difference in air defense in Syria after Russians came and modernize their systems and integrate them in IADS comparing to situation before, when every battery was on its own. IRIADS is far bigger than Syrian AD and majority of their complexes are domestic, so sanctions could not degrade their capabilities. They produce their own spare parts and missiles. IRIADS actually is not a joke.
Syrian are disapointed with chinese radars who invest like 100000x more than iranian. Let alone iranian sytems that looks more like toys than anything else. Stop blinding yourself with your hate of US.
Even russians include US made electronics in their last radars because they can't produce everything and you think iran with its budget of some couple million dollars for all the army will do better.

Yes, IRIAF is small and old, but they are modernizing their planes and they are producing even new planes and helicopters. Same went for NAVY.
They can stop it right now. Those f-5 copies and missile boats won't go anywhere against US air force and navy.
Wrong again. In case of Attack, Iran will strike back and destroy US bases in ME as well as all oil instalations in KSA, UAE, Qatar, … They will also sink US fleet in persian gulf. They have enough anti-ship ballistic and cruise missiles to do the job. US is in no position to fight long war with Iran, because they are bankrupt state. With no money, US army will fall apart.
If an attack occurs it's gonna be US+KSA+israel+gulf states+ UK+ some EU states.
US are not stupid, they know what are iranian capabilities. If it goes hot they will leave the bases, deploy troops outside with their vehicles, send the fighters/bombers out of reach of iranian missiles. Most of their ballistic missiles are not all 2500km ones but smaller.
For the antiship missiles you should check a map. The strait is very small but then the persian gulf is 350km max. Their antiship missiles have not that range. Most are chinese equivalents of older exocets and kh35 which are better than iranian equivalents but still have less than 300km in range.
The US carriers won't even go there. They will attack from the south.
Saudi arabia is planing to buy S-400 which will intercept any of those iranian scud variants. And if they really need something fast they can buy S-300VM.
