Jait is right
the Borg were ALREADY coming to federation space. Why ? Because of a temporal loop. A Temporal Loop that includes the events of ST: First Contact and an episode of ST: Enterprise (this episode exactly)
Q, trowing the Enterprise to the Borg in the episode "Q, who?" allowed them to prepare. Without this warning the Federation would have been completely and utterly fucked
