To whit, I think most US Citizens would disagree with the concepts of:
The concept of Launch On Warning - an artificial time clock to respond that requires fallible humans to make decisions of enormous consequence before being informed of all available information
POTUS having the sole launch/release authority
There really aren't any good alternatives to 'Launch on Warning' and the President having sole launch authority in many cases. While they are far from ideal they are the 'least bad' option when faced with a possible large-scale nuclear conflict.
Added to this there is no recall of a missile, and a missile past the boost phase is impossible to intercept. My guess is most Americans believe the US is protected from attack when in fact the capability to intercept an incoming missile or warhead is impossible.
That is incorrect, almost all operational missile defense systems intercept missiles past the boost phase from Patriots to THAAD and
Ground Based Interceptors. It is not impossible to intercept incoming missiles or warheads and it has been done many times, particularly in the last few years. It is not easy though and it is very expensive, with each individual interceptor usually costing $ millions. The quandary is that the longer the range of the threat usually increases the difficulty of intercept that translates into increased cost, and that is the reason we have only a limited number of GBI's that are capable of intercepting ICBM's.
This is a decent, simple and accurate overview of how the intercept of a longer-range missile, in this case an ICBM warhead intercepted by a GBI, would work. All parts of the Ground-based Missile Defense (GMD) system depicted are operational. As I mentioned though every piece of that intercept system very expensive though, with some parts costing $ billions.
