A couple questions:
For instance: assuming Wyoming is the state which becomes New County: would being born in Wyoming mean you are a citizen of New Country?
Who will adjucate conflicts between Indians and New Country?
A one time payment apportioned by population vs entire population of the USA at the time of the secession.
The USA pays SSI retirment benefits to it's citizens, mostly based on the continuing inflow of revenue to the SSI program. Assuming SSI contributions will not be required in the new country, do you expect SSI benefits to continue to be paid by FedGov to citizens living in New Country after the split?
"Assuming SSI contributions will not be required in the new country," which is a false assumption. The new country(formally a state) will now collect payroll taxes and distribute them. That will be in the article of secession. It's up to the people of that state to decide.
US military veterans receive healthcare via the VA. Will New State take on the care of veterans of another countries veterans (USA, that is). If so, for how long. Who will pay military pensions for US Veterans living in New Country?
The USA pays veterans that live all over the world. It would be up to them to decide if they are going to keep paying. As far as current VA benefits, the new country can decide to keep up the VA in their new country or not. My guess is they will. It is up to the people to decide.
Who will be allowed to move to New Country after the split.
I would suggest an open border period of a year to allow the deadbeat liberals to vacate red countries and vice versa. Emigration would be highly recommended.
Who will be considered a citizen of New Country after the split?
Um, the citizens of that former state.
Will it be Jus soli or jus sanguinis, or both. For instance: assuming Wyoming is the state which becomes New County: would being born in Wyoming mean you are a citizen of New Country?
Yes.
How about having two parents born in Wyoming?
Great, they are citizens of the country of Wyoming or whatever name they choose.
Will New Country honor the treaties made between Indian tribes with Fed Gov?
I guess so. Or not.
Who will adjucate conflicts between Indians and New Country?
The President (former Governor) of the new country.
As I see it there is no new country, it is still the good ol USA. The blue counties are expulsed by the US for violating federal law, for sedition and as a threat to the US Constitution. Counties will vote to reaffirm their allegiance to the Constitution and the federal government. Counties that vote against will be expulsed unless of strategic importance. People in the wrong county are given a reasonable amount of time to relocate.
