Really, Nuku-Nuku by herself would be an unstopable force against any conventional army of the time. On the other hand, Nuku-Nuku doesn't really want to hurt anybody.
However, I don't think Nerima here would be in a position for expeditions that far away for a while, because they aren't just up against conventional forces if this is the Inu Yasha past. With Fluffy and Naraku out there, tanks aren't quite as invulnerable as you might think.

No, I don't believe the world has gone mad. In order for it to go mad it would need to have been sane at some point.
