Another pointless thought exercise.
If you take a single system and pitch it against a network of systems from the OpFor's military designed specifically to counter it, of course the single system gets thrashed.
The conclusion was decided by the setting of the scenario.
But that is nothing like reality.
In any realistic scenario, the long range SAM would be backed up by friendly fighters and long range OTH radars as well as being screened and protected against attack by shorter range missiles, AAAs and point defence systems.
Against a competent adversary with an integrated air defence network and its own stealth fighter force, what would happen is the bomb truck and F35 gets picked up by long range OTH radar long before they are within the engagement area. A pair of PAKFA/J20s gets vectored in, takes out the F35 and then smokes the bomb truck.
Even if we rule out defensive air power altogether, what would happen is OTH radar detects the incomings, frontline SAMs goes dark while ones further in goes active to bait the trap.
As the F35 starts trying to locate the active radars, SAM radars light up right underneath it and blows it and the bomb truck away.
Even if we strip good strategy, OTH radar, other long range SAMs out, and just put some Tors and/or LD2000 CIWS by the long range SAMs, its swarm of low cost missile equation gets turned on its head and the odds against and costs of successfully punching through all those defences climbs exponentially.
That's all entirely ignoring ECM and jamming on the defender's side.
If the Serbs managed to spoof full spec HARMs and ALAARM ARMs using a slightly modified microwave oven, imagine what modern day dedicated jammers and decoys could do to stripped down throw away cruise missiles.
