What better way to stop fighting , if you don't want troops on the ground, then to create a mass exodus of their fighting age men so that their number of recruits are not there to fill the ranks.....get enough out of those countries and you can go in fairly light and take over...or change leaderships.
Next stage is for the fat cats acquire the resources of the country...Africa comes to mind....rich with resources but hard to get to because of the many conflicts....get the young fighters and potential fighters out thru mass immigration and it's a good go for the resources....at worst “manageable”.......At the same time control the flow of 'human capital'....
Any border control enhancements will be to control that 'Human capital' flow and streamline it's system into countries for better efficiency...including our own.
Makes sense!
