I got a li'l drunksy wunksky after work last night -- apologies for flying off the handle.
A few things ....coming from an outsider:
(1) There are different layers of NMD. (a) The guarding against smaller areas using PAC-3s has been successful. There was a HUGE improvement between the two gulf wars in performance of the PAC-3 -- it is still iteratively being improved upon, but I would guess it's a success. (b) The one being fielded in Poland (guarding larger area) is the same one that has undergone much testing in the pacific/Kwajalein. This has not been a stellar success, but "hitting a bullet in space with another bullet" is not done overnight -- it will have to be gradually improved upon to become a
reliable guarantor.
(2) With regards to 1b: some of the criticism is because every aspect of the system is being done for the first time, so when a coolant system does not perform perfectly the first time, some people will criticize it...when in actuality, as long as you know why it failed and can fix it....it's a "success" in my eyes. Same with other aspects of this iterative testing. You can educate yourselves on this topic by watching
this 2002 Frontline,...or reading
transcripts of experts' interviews.
(3) DCowboy was correct in that there is a limited window in time (in the atmosphere) that we are able to intercept, which is why "this layer" is crucial to enhance NMD's performance. However, other countries minimal improvements are not as relevant since we are spending more $, relatively speaking -- which leads to points (4) and (5).
(4) This is costing a lot, and I can't really argue with someone if they would rather see this $ being spent on other forms of defense, education or building a fence between us and Mexico -- it is expensive indeed.
(5) Technological gains made on this specific NMD platform/application go a long way towards other related platform/applications, such as space-based interceptors or whatever other applications they're working on which we don't (and shouldn't) know about.
(6) What Russia is really worried about (as they should be), is the precedent that this Poland/Czech installation is now setting. I'm sure there are many venues for relevant discussion, but I find
this site to succinctly point out all the relevant angles. This is really about the future, and we're leaps and bounds beyond anyone else out there. I have no qualms with someone if they'd choose to pursue a path of space assurance rather than space "weaponization" at some point...but, I'd rather us get as far out in front as we can for as long as we can before that happens. Russia has already misspent whatever strategic gains they may have made in this Georgia episode by our immediately agreeing with Poland/Czech on this installation...as long as the BTC pipeline is still in our hands.
(7) While I have already conceded that the $ spent on this system is indeed a lot, we should never totally pull the plug on it since we may never know when these iterative capabilities may become necessary (insert intelligence capabilities or lack thereof joke here). I'm not trying to be a fearmonger here, but if we suddenly find out in 2010 that Russian space/missile capability is far ahead of what we thought it was, and things don't happen to be going well between our two nations, you can't immediately "start where you stopped from" in a short time. The experts/technocrats/assets necessary fo this type of research have to be moving forward continually, though the pace (and thus $) can be argued about.
DCowboy and others are indeed correct when they say that the 1b umbrella isn't 100% effective...
as of now. But this is merely a step in a direction, one that can provide us invaluable information as to how we're going forward technologically in the future.
