Don't forget that old Cold War staple. "Deterrent Factor". When said dictator gets his war committee together to discuss whether a war with the US is winnable, sustainable, or at least costly for the US even thought they will probably lose, do you want his advisors to say, "the USAF just doubled their fleet of F-16CJ's, but we can really bloody their nose and draw out a prolonged air war."? Or do you want them to say, "The USAF just fielded the F-22 and F-35, we can't see them, we can't detect them and just one of those airplanes can knock out many of our fighters and bomb our cities and airfields invisibly. We don't recommend a war at this time."? And if they actually are crazy enough to start a war, that threat is real not just disinformation. I'd rather have a laser gun and never have to defend myself than have the latest hottest rifle and have some criminal say, "I can probably take him!"

do you really beleive that F22 and F35 can pass undetected by S300PMU2 and S400 air defence systems?

I think the better question is whether S300PMU and S400 users think that they can effective defend their airspace when each battery can now only protect a 40km area vs a 400km area, and the seekers of each one of the missiles they do get to fire can only acquire the target at say 2.5 km vs say 25km greatly decreasingly their PK. The same goes for AWACs and fighters.

the Isrealis have recently shown how vulnerable Syrian (Russian) air defense networks were when they made the strike on the nuke facility back in the fall. Russian "experts" were reportedly so stumped as to what happened that they made a trip to Syria to figure out what happened.

...these are muslim countries with low education officers,soldiers, population etc...in war 1999 in Serbia,NATO managed to destroy only 13 Serbian tanks for 78days of bombing because Serbian army had a lots of forests for hiding and puting fake tanks made of paper and wood...stealth improves,but doesnt make plane invincible...F117 was shot down in Serbia 1999 with 30yrs old system NEVA,and 2 more were damaged...if you want to survive,you must be smart to hide and deceive your enemy...Serbian engeneers were making fake airstrips and fake MiGs29 of thick paper,dressing dolls from stores in military uniforms etc...

THe Muslim incompetence is a myth realy...
What hinders them from being combat effective is the doctrine they learned from the russians plus their equipment.
This has been proven in the 1973 war when the Egyptians where the laughing stock of russian "experts" so Russia sent 130 planes,+ pilots, SAM bateries and 20000 men to operate them, wich... hummm didnt quite improve over the egyptians either.

There was a soviet strategist that wrote, that the result of the defeat in the AA scenario was over dependence of ground based anti air defenses along with a serious lack of ELINT and capable auntonomous combat systems electronics onboard of the highly GCI dependent Fighters. A lesson that the Israelis have learned long ago and correctly apply it with the right equipment. I am not surprised they can penetrate those old russian made defenses, at all.

As for the Serbia, they were very smart but could only take desperate measures. The conflict was lost to them from the start anyway. The F-117 downing was the rusult of positioning of defenses given the fact that the same plane was flying over the same flight path every night. It didnt require guided weapons to destroy it at all. Stealth is not dumbass proof, its a measure to increase survivability and does not discart the use of proper tactics.
