~What if these 600,000 residents of Alaska voted to become part of Russia?~
Won’t happen. Crimean parallels are far-fetched. They went to Russia because Ukraine is a corrupt hellhole circling a bowl between anarchy and tyranny of all colors for 20 years and counting. Alaska is a part of country which is both a top or second global economy and also in a top ten in terms of freedoms.
Southwest is not going to Mexico anytime soon for that very reason.
I agree. Same with your comment about the southwest returning to Mexico.
