Annex Mexico.
Have the Army go in and restore order, and then institute a territorial government.
Rather than collapse the sovereignty of The United States of America in a NAU, that is one solution that has merit, BuffaloJack; Other possible solutions BUMP; BUMP!
Thanks for the ping, AuntB. Very interesting.
Sure, annex Mexico and give Obama and Democrats the opportunity to re-write our constitution with regard to our new territory....as it will be a new nation with greater responsibilities and more gov't safeguards.
