MAD in a good illustration is like 2 gunmen each equips the gun
which can mutually shoot each other, the missile defense system
that the yanks are pursuing is like the bullet proof vest to be
worn by the affordable one of the 2 gunmen, who got the edge
between these 2 gunmen is obvious.
Yanks deployed ICBM/SLBM with multiple/Maneuverable RVs as early as
1970-1980s, while Russians only just started deploying land based
Topol-M with similar capability. As I said, SLBM like Trident D5 or
ICBM like Minuteman-3 which feature GPS midcourse and Radar
terminal guidance are in very high accuracy ( Usually CEP < 50m)
and further more, because those RVs are with terminal guidance
& fins, they are maneuverable, which makes the terminal phase
interception by other missile within the atmosphere impossible.
Russians & Yanks are well aware low tie ABM systems like
S-400/PAC-3 are incapable to intercept such maneuverable RV. The
most vulnerable moment of the ICBM or SLBM is during their launch
stage ( now most guys should understand why Yanks are so aggressive
to deploy ABMs just to the doorway of Russians that makes the
latter so annoyed), to a less extent, in the midcourse of the
ICBM/SLBM, while Yanks NTW anti-ballistic Missile systems at work,
finally, its the ICBM/SLBM last moment just before re entering the
atmosphere, when the last defense of THAAD at work. Once the
Maneuverable/Multiple RVs entered atmosphere, sorry, only God can
stops the impact.
Thats why, only furnishing a gun is not enough to give you the
edge, especially your gun has no edge at all over the others.
meanwhile, you have to figure out ways to comprise the others
bullet proof vest, how to do it? Well, you know Yanks many ABM
systems are space based, try to destruct such space asserts, say
developing your ASAT ability.
