However, the moral of the story still remains, NEW Top of the Line
Russian SAMs and ABM systems are the BEST IN THE WORLD and always have
been

That's quite a leap, between how good the SA-6 was 30 years ago and today.
BTW, did you hear of about the Hawk and its various improved models? PK beats
the SA-6. I think Russian/Soviet propaganda is the BEST IN THE WORLD and
always has been.

S-400 would give the IAF or any
airforce even more trouble than the SA-6 gave to the IAF in the Yom
Kippur War.

Only if no lessons were learned in the past 30 years. You may think that is
likely - you'd be wrong. The IAF had NO experience against SAMs prior to that
first slaughter. That's obviously changed. The losses that occurred later in
the Bekaa Valley and elsewhere took place during engagements where often dozens
of missiles were launched at targets that were already engaged in dogfights
with other aircraft - but in your mind, the IAF wouldn't have learned from such
encounters? Bright one, that's foolish.

The S400 has been touted long and hard as the latest and greatest SAM,
practically since the first pencil drawings of it were made. It'll be a LOT
more impressive if it makes it into combat and lives up to the dreams; until
then, its simply not the BEST IN THE WORLD! at anything.
