Firstly Re the claimed 100% is pure unadlterated bullshit. Nothing ever has a 100% kill rate, and oif someone claims they do, they are lying.
F-15 combat aircraft have 100% success rate in (strictly) air-to-air engagements; 102 in total [all conflicts].
My point is that PAC-3 have intercepted every kind of target that came within its reach in various battles - this is 100% intercept record for it in the battlefield.
Now, I am (not) asserting that these weapon systems are
infallible, they have their limits and are designed to defeat specific threats. However, they are really good at what they are supposed to do - and this fact is important to consider.
Secondly, re rest of your links. Big fucking deal. So they can hit an uncomining warhead. Repeat. wBig fucking deal. People could do that in the late fifties. Even in the second World War, they had plans to use RADAR guiuded guns firing enmass to intercept V2. Thats irrelevant. No one is throwing 40's era Scud, or fifties era R-7 missiles at you. Modern (by which I mean any BM designed since the 1960's) have penetration aids, such a jammers, chaff, balloons decoys. They also have high altitude maximum trajectory and very high (mach 8) terminal velocity, as opposed to the sub-sonic terminal velocity of the Scuds. Not to mention MIRV's and maneovering warheads.
Minuteman-III ICBM came into service in 1970 and it is one of the most advanced ballistic missiles in existence even today. You don't look at how old a missile is [unless it is really ancient]; you concentrate on its capabilities in large part.
Scuds might be old but they are a threat to large stationary targets and have claimed many lives in wars - and some variants are not easy to intercept due to their erratic behavior.
More importantly, different classes of ballistic missiles exist today and different ABM systems have been developed to counter each class of ballistic missiles accordingly. To put this in perspective:
PAC-3 is suitable for intercepting SRBM and MRBM class targets; THAAD is suitable for intercepting SRBM, MRBM, IRBM and ICBM class targets (in terminal stage of flight and/or a bit earlier); and GMD is suitable for intercepting MRBM, IRBM and ICBM class targets (in both Mid-course and terminal stages of flight). Idea is to make defenses against ballistic missiles multi-layered to increase chances of intercepting them and relevant coverage.
As for the countermeasures, do you know that interceptors of THAAD and GMD systems can distinguish real warheads from decoys? They cannot be fooled with this strategy because decoys do not behave like real warheads during re-entry phase and there are technical methods to distinguish them in exoatmospheric conditions also. Even maneuvering warheads cannot escape these modern interceptors due to their on-board tracking mechanisms and sheer speed:
The Raytheon EKV is equipped with an infrared seeker, which is comprised of focal plane arrays and a cooling assembly attached to an optical telescope. The seeker software has to detect and track all incoming objects, discriminate warheads from decoys, and steer the EKV to a head-on collision with a target at closing speeds of more than 25700 km/h (16000 mph). The EKV's manoeuvering system, known as DACS (Divert and Attitude Control System), has four rocket thrusters around the vehicle's body. The vehicle weighs approximately 63 kg (140 lb), is 140 cm (55 in) long and about 60 cm (24 in) in diameter.

The only method to get through these defenses is to deploy ICBM in relatively larger numbers. Only Russia have this advantage at present. However, US is expected to expand its defenses against such threats in coming years.
I believe that existing form of MAD between Russia and US will be obsolete at some point in the future, like 30 years ahead from today.
There is a reason everyone gave up on missile defences in the early 70's; after nearly 25 years of work and getting technically more advanced than anything now; its just not feasible. (The US Safeguard System; google it, was more advanced the the much vanted GMD, and was decommmssioned since all it could do was protect a small area).
Bro, you have no idea how capable GMD system have become in recent years. Its protection extends to entire North America (from Mexico to Alaska) and its tracking assets are deployed at land, sea and space across the world to ensure intercepts at vast distances.

There have been considerable advances in science and technologies since 1970 and what seemed to be an impossible objective back then, is becoming a reality in current times.
Several states are investing in 'missile defenses' today and they are on the right path. You don't take your chances, if you have a strong economy and take your national security seriously.
The other MOKV that you linked to actually made me cry with laughter. Its a rehase of
Brilliant Pebbles, the only SDI project that seemed feasbily; except Brilliant Pebbles was supposed to be orbiting interceptors, while this is ground based; in othger words the compolexity of Brillinant Pebbles, with the disadvantages of Ground Based systems. Brilliant Pebbles also was ulimatkey deemed unworkable.
In short, don't be seduced by marketing departments, or the IDF propaganda arm (for
@DavidSling).
I think you do not understand the concept of MOKV.
Technically, MOKV represents an MiRV'ed interceptor much like an MiRV'ed ballistic missile; a single interceptor will carry multiple kill vehicles and release them to intercept multiple warheads in exoatmospheric conditions.
MOKV will make it technically feasible to intercept a large volley of ICBMs in space with relatively fewer interceptors. This is the next step in evolution of GMD system.
As for the brilliant pebbles part, this may surprise you but US is also considering development/deployment of strictly space-based defenses against ballistic missiles in near future. Here:

Essentially, another layer of 'missile defenses' on top of existing layers.
