Also, shooting down rogue nation launches has value and any hand-wringing over 'destabilization' is fairly ridiculous as nukes have counter measures and are launched in numbers that make it impractical to shoot down in mass numbers. The US's very limited shield may stop Iran or N Korea from hitting a population center (Tokyo, Tel Aviv, etc) but won't stop nuclear war with China or Russia if a full launch happened. There is no practical counter-measure over hundreds of ICBM's, sub launches, and bomber launches with many warheads per missile.
