Seriously, that's just stupid. I mean, I'm not going to say war is good, but there are at least good reasons for it, sometimes. That, though, that's just a pointless waste of life. Machines? Really? That's what they rage against? Was the world such a great place at that point that there wasn't something legitimate for them to be pissed off about?
Nobody ever considered that maybe the giant monster was just a giant monster?
