It doesn't work. It's a scientific impossibility.
Nukes and ICBMs are fake. The "science" is fake.
"Critical mass" makes no sense. Radiation levels have never been shown to vary with mass.
An ICBM would burn up on re-entry through the atmosphere just as a meteor would.
Everything you believe to be true is very likely to be false.
