What darned difference does it make whether "NZ" is upset or not??? Look, this guy may be guilty of nothing more than his own mother's bad tste in men...
But it was in NZ that he started filling out the peperwork, was it not? So who screwed up, most likely?? NZ did..."those stupid Americans have changed everything so much, we don't even know if we've got the right paperwork (Add epithets about red tape as needed) ...
AND/OR "We're not sure we've got the paperwork straight, but the stupid Americans won't be paying attention anyway"
Either way, NZ is at fault as well, and they have NO RIGHT to be playing "innocent victim" here.
