Enough of all these political drama, Native America vexed, ask every other nationalities to go home. What will be the fallouts?

The native Americans are tired of the phenomenon of dominance and control established by the European illegal immigrants' progeny in their God given land. The natives educated them on how to survive in their territory, they turn around to kill them massively to the point of extinction. All kind of human right violations were placed on the natives til date. Now the sons and daughters of immigrants (illegally of course) making laws to cut people running away from violence in their native countries to stop them from entering the United States. Now, the Native Americans decide to make a 3.00 AM announcement and it goes thus: every nationalities have thirty days to go home, vacate our land peacefully. Would there be a peaceful resolution of the order or would there be civil war with a lot of violence? Is it fair to take people's land and power from them? Would all the immigrants respect the natives and depart peacefully? Can the Natives manage the country by themselves? Your thoughts?
