"only vested interest I have in this subject is the preservation of my life and that of my loved ones."


Then you are failing in self-interest. IF a missile attack is ever made ( "the scenario I described") , you are accepting that the missile WILL impact ( since we will not have a way to intercept it and then decide, taking enough time to get it right, WHO to hold responsible) , and that the US WILL retaliate. This does not bode well for your, or your loved ones, survival.
