This document doesn't say that somebody in the U.S. can be targeted without a warrant. It says

For these reasons, we hold that a foreign intelligence exception to the Fourth Amendment's warrant requirement exists when surveillance is conducted to obtain foreign intelligence for national security purposes and is directed against foreign powers or agents of foreign powers reasonably believed to be located outside the United States.

Not the same thing.

Aka, FISA warrants and FISA courts which in practice haven't been limited to foreign spying for... decades? now?
