Dog fighting is not a serious concern in modern fighter combat because missiles have gotten so effective that the current strategy has been forced into beyond visual range combat. And stealth doesn't just "fail". In bvr the first side that sees the other is the side that gets to fire a salvo first, which is the primary advantage of stealth technology: so that the enemy doesn't see you from as far as you can see them. All stealth does is linearly lower the radar return of your plane for a given distance and angle, but radar return is inversely proportional to the fourth power of distance. This means that if you get close enough then any decent radar can eventually make out an f35. The whole point of stealth is to make that distance as small as possible.

"Dog fighting is not a serious concern in modern fighter combat"

We heard this before and it was a disaster.

"And stealth doesn't just "fail"."

Nothing is invisible. It depends on your frequency that you use for detection and other technologies. You will find out if your are "invisible" for an able opponent (speak, China, Russia, not Iran) in battle. But then it may be too late.
