As I said, they are torn. Now you feel my pain trying to lock this stuff down.
For the Russians, they are sort in agreement that it would be easier to offer them citizenship rather then fight as they are a fairly good sized force to deal with.
The Mexican military is a mixed bag. Most have turned marauder, they did invade the country and kill Americans in the process. But since they are not nearly as big of a threat as the Russians, the group is considering taking them out entirely. Although my position is for the groups that are still coherent military groups, they are added assets.
Now the Mexican refugees/civilians are more complicated actually. Most of South Texas is Mexican refugee nowadays, from mexico itself, according to Cannon. On the one hand, forcing them out is gonna be hard to do as most will just run away and hide. Two - that will cut the population by 60-70% in South texas, whos gonna do the work? And Three - they are just civilians, not active military shouldn't we help them if they want to stay?
