Yup. A lot of the proposed countermeasures are absurd and reek of pork. There
are several cases of high price tag countermeasures with no realistic utility.
An old shipping vessel can be purchased for less than US$1M, and packing it to
the gills with Chinese bulk explosive (the Chinese export thousands of tons of
explosives around the world) would be cheap and completely legal.
Another fine example of this is the proposed man-portable surface-to-air
missile countermeasures they've talked about installing on all commercial
passenger jets for some crazy amount of money. Old and readily available
MANPADs like the SA-7 are nearly useless against commercial passenger jets (way
outside the design spec for a weapon that was marginal even in its day),
rendering countermeasures largely pointless. Modern and very difficult to come
by MANPADs are nearly impervious to the types of countermeasures they are
discussing, but they are not going to be installing state-of-the-art classified
SAM counter-battery and active intercept technology on commercial jets, again
rendering such proposals pointless.
They would be better off using that money for direct intelligence operations.

They would probably have point-of-origin pegged within seconds of launch and
before it lands. There is a legion of satellites orbiting for precisely this
purpose, never mind ground-based radar. Like you, I find the notion absurd.

The Patriot was an anti-aircraft system, but by good fortune of being
over-engineered for its intended use, had modest capability at intercepting
ballistic missiles. As you point out, it proved to be almost worthless because
ballistic missiles are harder targets than aircraft and will happily continue
on their course even if jostled a bit by a SAM.
After that war, they re-did the software and warhead to have much more efficacy
against ballistic missiles, but it is still just an over-engineered

Missile Defense is completely viable, but they have had a lot of teething
problems with one of the fundamentally new technology platforms they were
counting on that has delayed deployment by quite some time. Since many
unrelated weapon systems are relying on this same technology and they have made
a lot of progress in getting it working reliably, it is just a matter of time
before they deploy comprehensive anti-missile systems that range from tactical
all the way up to strategic. We've been hearing less about it because it has
been working better. In the near future, there will be no distinction between
surface anti-aircraft and ABM weapon systems; they will all be hyperkinetic
"hit a bullet with a bullet" technologies -- technology convergence.
I do not think many people understand what is currently unreliable about ABM
technology. It is NOT the ability to "hit a bullet with a bullet", as the
discrimination and guidance system works almost flawlessly and has been
deployed in other weapon systems for a number of years now -- guidance and
discrimination packages are heavily re-used once perfected. Contrary to some
speculation to the contrary, this particular package is almost impervious to
countermeasures, decoys, and spoofing. Very capable weapons like the new
generation AIM-9X Sidewinder use a cut-down variation on the same guidance and
The technology problem has been a brand new rocket platform, that is supposed
to eventually replace most existing rocket motors platforms in use by the US
military. The Army was the first to bite the bullet and commit to these new
rocket motors for all their new systems, and have had a number of problems as a
result. The Navy was more conservative and has deployed the same ABM guidance
package on their old proven rocket platform and it has worked perfectly for
them, though without the advantages the new rocket motors offer.
The specific problem is that the new hyperkinetic motor platform generates
extremely high acceleration and peak velocity that is pushing the engineering
envelope right up against the limits of materials science and requiring the use
of the most advanced exotic fabrication and materials the US knows how to
produce. It has spectacular range, closing speed, and terminal performance if
you can keep the bloody thing together in flight, and because it moves so fast,
you can count on a kinetic energy kill. All in a very compact package. There
is footage on the web of small hyperkinetic rocket based weapon tests being
used against armor at a couple miles range. They make normal missiles look
like they are standing still -- it is something to see.
Most of the other missile defense deployments that have been going on are
stopgaps until they can get the rocket motor platform to function reliably
under all environments. Once they figure out the engineering loose-ends, ABM
capable weapons will become prolific in the US arsenal. It might not be a
national missile defense as originally envisioned, but that technology will
create a de facto national missile defense. Once they get the bugs worked out.
