In another article, which I cannot track down, the point was made that there are literally thousands of young people in foreign countries who have spent almost no time in the U.S. except the time it took to be born. All of these are entitled to a U.S. passport.
Imagine the national security issues involved in some of these individuals becoming terrorists who have an absolute right to enter the U.S. legally and stay as long as they choose. You could think of them as "reverse sleeper agents." This situation is a security nightmare.
