We aren't overpopulated. The issue is mismanagement, a lack of integrity and steep levels of corruption at virtually all levels imaginable. No, it's not just people with large facial features, there's plenty of other secretive groups, even some who use others to obscure themselves, who infiltrate and cast silent weapons, all with the aim of corroding. The break all of the toys before the exit shit is self-destructive but these groups don't care. There's a difference between not making things too public so there isn't more bloodshed or witness than there needs to be and self-destructive behavior that ruins things for everyone. At a certain point we have to realize that people who would blow up the planet over a territorial dispute probably shouldn't be on the planet, much in the same way you wouldn't keep sitting with the kid that tries to eat everyone else's lunch at the lunch table. Maybe *killing him* isn't necessarily fair, but entertaining him certainly isn't worth while and not being suspicious of him should will probably get you in more trouble than needed.
