To offer a bit of context, the same government just voted to raise current pensions at the expense of steep taxation hikes for current workers, made massive cuts to social services, and is now discussing military service. This generation is rightfully feeling like they're getting a sore deal.
So it could be:
- the native young population who are now flocking in the AfD
- the people fighting the AfD in the street
- the second generation immigrants born there
- the very recent immigrants
- a mix of all
Because the alchemy of creating a working army and "esprit de corps" is much harder than in a corporation. You cannot just take a modern managerial approach to creating an army.
A mix of all will end up obviously in a disaster but selecting on any group will end up in a civil war or coup.
