While that's funny, it's quite inaccurate to portray a North American tribe as having a legal border and immigration law. Just more of that nonsense justifying illegal immigration by non-white people because "whitey was the original illegal".
Mistake #1 - They allowed uncontrolled immigration.
Mistake #2 - When they finally became worried about the uncontrolled immigration, they asked the French for help (French Indian War).
