Citizenship has to do with natural allegiances. “Natural” and “native” are terms used in national and international law regarding citizenship. Citizenship allegiance is tied to the land where one’s parents are from. A “natural-born citizen” refers to biological birth, not geographical birth. “Native-born” refers to geographical allegiance. If a person becomes naturalized he goes through a lawful change of allegiance from one country to another. If a child is born after the parent is naturalized the new allegiance applies to the child as well.
If an invader gives birth during an invasion no allegiances change for the child anymore than for the invader. The child is tied to the parent by familial bonds. The citizenship does not change by waiting long enough. There is no time limit on prosecution. Though it may not be considered a heinous crime it is still a crime to invade what is not your own home. A country is a home.
At no time or place in history was invasion considered a legitimate form of citizenship. There was either a first time occupation of land, war or treaties with other parties making claims.
Although the U.S. government has been negligent at best and treasonous at worst regarding defense of its international borders, the primary guilt still resides with the direct perpetrators, the invaders. The invasion has been to the tune of 30-40 million. If they had been wearing military uniforms instead of coming dressed as civilians do you think government would notice?
This is treachery to the owners of the country, the people. It does damage to them by stealing from them their resources to conduct their lives without being undermined with crowding, extra costs, job losses, dilution of resources, undermining of wages, etc. All the unpleasant thing that would not be there normally. It also does damage to the invaders’ country by taking pressure off their government to deal with its problems rather than sluff those problems off onto the U.S.A. and its tax payers.
The job market gets undermined. When the lowest wages get lowered even more the entire wage scale gets pulled down because there are more and more people who will do-it-for-less just to have a job at all.
