Humans acting like arrogant idiots isn't new... hell, in TNG Picard was like "We've got this Q, please leave." Then suddenly Borg are a problem, who due to time shenanigans involving First Contact and a later episode of Enterprise had been incoming for years.

Say what ya want about Q, he never alerted the Borg to the fact that the Federation existed, he warned the Federation that the Borg existed and were coming.
