We still utilize Minuteman IIIs, which are getting to be almost 30 years old. China upgrades it nuclear forces? That's money they aren't spending to improve the PLA and PLAN to try and invade Taiwan. Numerically limited and technologically primitive doesn't mean that taking out, for example, Seattle wouldn't be a bad idea if the state is close enough to collapse that they're going to be stuck up against a wall. Maybe we don't have a SSN in range to be able to hit the target. If it actually launches, we don't have anything to do.Patrick Degan wrote:They are the only serious ICBM threat which would justify even the attempt at an ABM system, and the recent statements by Vladimir Putin indicate clearly that Russia will not simply allow its nuclear force to be rendered impotent by the country which remains its most logical nuclear adversary —in other words, us. China hasn't upgraded its nuclear force significantly in 30 years (though our attempt at NMD may cause them to rethink that policy) and whatever capability North Korea has is numerically limited and technologically primitive. Liquid-propellant ICBMs have to be jacked into launch position and fueled —a process which takes 15-17 minutes during which the missiles would be vulnerable to preemptive cruise missile strike launched from SSNs 30-60 miles off the Korean coast.Beowulf wrote:I see a couple assumptions you're making Degan.
We'll be facing the Russians in a nuclear attack.
There hasn't really been any impetus to develop a better decoys and such, because there hasn't been anything to stop a missile. And of course, it works both ways, they improve their decoys to decrease the effectiveness, we improve the system to increase effectiveness.Patrick Degan wrote:I hate to have to remind you of this, but the technology game works both ways.Technology won't have advanced since 1975 allowing us better ways to discriminate targets.
90% of a chance is better than 0%. When the stakes are the loss of one or more cities with casualties running into the millions in a nuclear attack, and you had a possibility of stopping it, then you're going to get raked over hot coals, as opposed to trying to stop it, and failing. How much damage would a successful attack cause? Millions? Billions?Patrick Degan wrote:When the stakes are the loss of one or more cities with casualties running into the millions in a nuclear attack, 90% won't be good enough. If the system cannot be guaranteed to stop even a limited attack (and this issue is still very much uncertain), then it is worse than useless.A system must be 100% effective to be worth buying
And of course, there's the sheer impossibility of something with a 100% reliability. The more nines you add to 99.9%, the more expensive it gets.
Lastly, just having the system puts doubt into the possibility of a successful ICBM attack, which means it decreases the chance of an attempt occuring.
And everyone of those missiles that is trying to saturate the defenses in one area, is a missile not heading for another target. And last I checked, Alaska is the next best thing to middle of nowhere. The only thing better would be a far out to sea platform. Targetting the system itself means you just used a bunch of nukes on the middle of nowhere.Patrick Degan wrote:Except they won't be "attacking the middle of nowhere". A serious adversary would employ a saturation attack to overwhelm the system. This has been discussed repeatedly not only by critics of the previous attempts at an ABM system in three decades (which included not only Pentagon analysts but scientists at Bell Laboratories —a primary ABM contractor in the 60s and 70s— during the Safeguard debate), but also by U.S. strategic planners designing the best means to overwhelm Galosh —the ABM system defending Moscow— during the height of the Cold War. The employment of decoys and other penaids also cannot be discounted no matter how much the present Cult of NMD wish they could be. A less capable adversary would seek other methods of attack which an NMD system is not designed to counter.Causing an aggressor to spend missiles attacking the middle of nowhere is not effective.
And massively increase the cost of their nuclear deterrant. Most countries can't afford to spend $450 billion a year on their armed forces. And of course, as the system get upgraded, they'll deal with this threat, possibly by hitting the warhead bus before debussing begins, as an example of what's possible.Patrick Degan wrote:To which a serious enemy would add more warheads, more decoys and penaids, and more warheads dedicated to an EMP strike —not for the object of wrecking the radar systems themselves but to heavily ionise the atmosphere; which would blind any radar system no matter how good it may be.That overwhelming a system can't be taken care of by adding better radars and more missiles.
