Scenario: United States of America Breakup and War

'Late in the day, on the 24th of January, 2021, many states started mobilizing troops of their own, and calling for an immediate breakup of the US. As the day progressed, every state had left the US, and President Biden had no idea what to do.'

January 25th:

Texas started invading New Mexico, Oklahoma, Louisiana, and Colorado in hope of regaining its stance as the most powerful country in North America. Kansas and Arkansas both joined in on the defenders side, claiming that "Texas has got to go". Texas drove deep into New Mexico, and Oklahoma, and had little offense in Louisiana, quickly nearing New Orleans. Louisiana surrendered and was annexed completely by Texas. New Mexico talked about peace but Texas leaders were very clear on their thoughts. New York mobilized 35,000 troops near their border with Vermont. Vermont counter-mobilized but was only able to mobilize 11,000 troops to defend with. New york crossed Lake Champlain and lost heavy casualties due to faulty weather and many Vermonters in their boats shooting at them.
