Boost-phase defenses themselves are destabilizing not only because of the necessity of predelegating launch authority, but because they must be placed near enough to North Korea to be effective.
Admittedly, boost-phase intercept approaches are still works in progress and not adequately funded.
First, although missile interceptors are increasing in range and altitude, more should be done to develop boost-phase intercept capabilities--that is, targeting enemy missiles shortly after launch, when they are most vulnerable due their relatively low speed, heavy fuel load, inability to deploy decoys or engage in evasive maneuvering, and susceptibility to tracking due to prominent infrared signatures.
Such maneuvers can prove effective against midcourse interceptors with limited agility, but they have negligible effect on an agile interceptor designed for boost-phase intercepts.
