because it's all the same arms race. If other nations build similar shields (not that many other nations would spend 10's if not hundreds of billions on something that doesn't seem to work yet), then it would eliminate the United State's ability to launch nuclear weapons at those targets, and the U.S. would engage in a counter measure. This is as much about the United States ability to use such weapons if it felt the need (and that is a big if) than it is about defending themselves against another nation.
And besides, almost the only scenario in which another country would launch a nuclear missile at the United States was if that nation felt it's own survival hinged upon it. The United States is not above invading other countries. If it found a way to bypass some nation's defence of nuclear arms, what's to assure those nations that the United States would not invade them? For some countries, the ability to fire nukes and have them land is seen as largely a defensive maneuver.
