Okay, that avoids one source of strife. But there's another to consider: Would that not give a foothold to enemy nations, such as the ChiComs, to buddy up to the 1 or 2 Leftist parts of our former country? Wouldn't the ChiComs send military "advisors" to open the door to Chinese troops, aided by native-born, snowflake trainees, to conquer and enslave the other parts of the former US?
And wouldn't the logistics of defending even one of the parts of the former US on a continent with no Monroe Doctrine become untenable?
We would have a mutual defense pact with four huge armies coordinating the defense of N.A. This is not hard.
To mitigate Chinese influence, the two American (conservative) parts of the former USA would need to form an alliance to forestall it. It has to be understood and accepted that the region dominated by CA will consider its connection with China a “special relationship,” not unlike that of the current USA and Britain. The key is keeping that rot from infiltrating the heartland regions.
This map doesn’t reflect Appalachia and breaks the red states in two. The red states stay united and stay the United States, the Blue coasts can call themselves Pussy Hats for all I care and effort would be made to dissuade unity between the coasts. In fact President Trump can declare that Blue counties that committed mass fraud to be in insurrection and send Federal Troops in. Establish military governors and change their status to non-voting commonwealths and rerun the election. Get elected for his second term and have the DOJ investigate the sh$t out of the Blue County Insurrectionists.
