This would be funny if you weren't serious. The development of MIRV warheads and decoys negated the possibility of significant intercept of ICBMs. Bush Jr backed out of the treaty so the US could develop an ABM system against rogue states with ICBMs (like Korea and Iran). It did not effect the ability of Russia to accomplish an ICBM strike in the slightest.
Since then, the US made a good progress in anti-missile systems and Russia is now being encircled by AeGIS complexes with SM-3. And though the latter is yet not capable to intercept even old Soviet/Russian ICBMs, in 10-15 years the situation will change
The Aegis system being used to shoot down ICBMs is absurd. It struggles to shoot down theater ballistic missiles. There's lots of work ongoing to improve that, but the notion that Aegis and SM3 could be upgraded to shoot down ICBMs, especially MIRV equipped ICBMs, is beyond absurd. THAAD
might be able to do a launch phase intercept,
if the THAAD battery was very close to the launch point
and had enough advance cueing to avoid any chance of a tail chase. There's no way to place a THAAD battery close enough to a Russian ICBM launch site to have even a remote chance of an intercept.
