Nobody is actually worried about that supposed compensation. The biggest joke going, is the notion that any of these technology improvements matter once you start lobbing hundreds of nuclear weapons at each other.

Bypass radar detection? Funny stuff.

The US has never thought it could stop dozens, much less hundreds, of Russia missiles. Fractional orbital bombardment system? A waste of money that Russia doesn't have, as one of the poorest major nations on earth (with a GDP per capita below Grenada).

Do you know why the US has spent so relatively little pushing nuclear weapons tech forward the last 40 years? Because it doesn't matter: just about everyone dies regardless. Russia has no missile shield, and the US has no missile shield that can stop a large volley of traditional missiles.
