"...the petition requires us to weigh the nation's security
interests against the Fourth Amendment privacy interests of United States persons."
The text Fourth Amendment doesn't narrow itself to "United States Persons". It says:
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

Why do you think 'the people' in the Fourth Amendment is not a reference to the same "We 'the people' of the United States" in the Constitution?
