Nobody will ever face off against the US Air Force... Jets are now mobile strike systems. Air defense systems are what competes with a nations air force, not other jets.
F-4's are incredibly lethal when armed with air-launched cruise missiles, glide bombs, etc. Nobody has to fly over a target to bomb it anymore. Absolutely no need for it.
100 F-4's armed with cruise missiles and glide bombs is equally as effective as 100 F-22's at this point in terms of offensive operation. It's a very fast and reliable platform for launching precision weapons. Combined with very accurate ballistic missiles, offensive operations have everything they need.
If the F-4 still had to fly over the target, that wouldn't be true obviously... the Asif cruise missile Iran just released has a 1,500KM range. That means F-4's could take off from Moscow and hit targets in Kiev without leaving airspace in Moscow. Yasin glide bombs have 50km range, which means F'4s could take off from the Russian side of the border and hit targets in Kharkiv and other border areas. The air-launched Qader cruise missiles have a 300km range, which means F'4s could take off from Sevastopol Air Base in Crimea, fly a short distance, and hit targets in Kherson, Odessa, etc without ever leaving Crimean airspace.
Make brand new J79's and AL-21's, copy the SU-22 and F-4 airframes, and Iran will have a modern bomber fleet for this generation of warfare.
