Wild Weasel literally is baiting SAM to shoot at them. That's the point of Wild Weasel, you bait the RADAR then kill the air defense before they lock in on you. Any RADAR works by emitting radio waves, and those radio waves can be tracked with a homing missile.
Just looking at the wild weasel causes the RADAR system to possibly be bombed. SAM installations vs Wild Weasel tactics are very complex.
In any case...if your SAM is too scared to engage with the wild weasel, they just bomb you from 12,000 feet altitudes.
Winning at 12,000 feet altitudes 50 miles away is the point of the US Air Force. Their goal is to never even engage at lower altitudes until they know they have won in the standoff, long range game.
Using drones to bait them like in Baghdad in 1991 would work too.
How would something like that help Ukraine? Does Russia even need HARM when they have so much artillery they can just turn the surroundings of the radar site into the surface of the moon? My understanding is Ukraine preserved its air defenses by moving them right before 2/24 and is betting on Russian cruise missile avionics and military intelligence sucking.
Drones won't work for stealth because you need the radio-wave link.
F35 is better because the pilot can turn off all communications when doing the SAED mission, forcing the enemy RADAR to increase their power to even try to see the F35. I don't think drones are in a position (yet) to go radio-silent and accomplish their mission.
