But then again, all effective methods of defense against the Borg could be considered genocide. Its the circumstances that necessitated drastic methods. The federation had no real defences and faced a very real threat of extinction (in the sense of being individuals) from the Borg. It was one of those situations where they had to fight back with as much force as necessary.
