Missile defense is a misnomer. The distinction between a defensive and offensive capability is meaningless in the context of arms races and mutually assured destruction. As we pour billions into shooting down ICBMs, China will pour billions into new delivery systems to evade that defense, and vice versa.

The net result is that money on all sides is taxed away from things that people actually need and want (food, shelter, medicine, schools, parks, the arts) and directed into things that either rust in silos and bases or kill us all.

The only way to stop an arms race is to increase transparency and to negotiate treaties with our peers.
