AH ONLY THEY HAVE (USA ) HAD F-4 OF 60S AND MAY BE USN HAD F-8 ON THEIR CARRIERS REST OF OF THEIR RELATIVELY NEW JETS (F-16/f-15), AND THEN THEIR (USAF) CONSIDER THEIR F-15/F-16 AKIN TO F-22/F-35 IN FIRST GULF WAR
That is a misleading parallel.
F-14 ; F-15 ; F-16 ; and F-18 = all 4th generation class of 1970s origin. Russian MiG-29K was of the same class.
Similarly, much of the equipment in American hands in 1991 was a mix of 1960s, 1970s and 1980s origin across all spectrums (Air - Land - Sea).
Real breakthrough was in the spectrum of
infiltrating techniques with introduction of LO class cruise missiles, helicopters and bombers in the mix - stuff that was largely unknown in public discourses back then.
Americans utilized those tools in conjunction with powerful EW assets to great effect in 1991 to disrupt Iraqi C&C infrastructure, energy sector, and activity in Iraqi military bases in the cover of darkness across the board. Iraqi military machine fell into disarray in the face of an unrecognized model of warfare because they were trained and equipped to fight a different kind of war - the war that was entrenched in Soviet psyche back then.
Iraqi Air Force could not operate in the manner it was intended to while subjected to precision strikes from cruise missiles and LO class bombers which could evade radar detection. Those brave Iraqi pilots who somehow managed to take the fight to Americans in the AIR, were up against odds they could not hope to contend with, individual merits of MiG-29K and Mirage F1 notwithstanding.

F-22A and F-35 variants = entirely new class of warfare capabilities with mating of VLO, 4th generation warfighting concepts, and sensor fusion in the mix (intelligent machines). This is revolution in the making with no true analogue in history.
How about Russian/Chinese air forces they are quite comparable to USAF
No, they are not.
