I've discussed the concept that we're in the early stages of a civil war in this country a number of times; enough so that I feel no urge to rehash it. Let's look at another issue: Can we stop it before it gets out of hand?
In a number of science fiction books and series I've read, space travel and immigration to new colonies and planets served as a sort of "safety valve", allowing those who were fed up with the situation here on Earth (or another long settled world) to pull up stakes and leave for greener pastures. Obviously, we aren't in a position where we can do that just yet.
However, another possibility does present itself. I've read various predictions that the US might break up, a la the old Soviet Union. Igor Panarin is one of the better know of these, predicting that it would happen in 2010 after a civil war. History proves that he was a bit off with that prediction, though it may yet prove accurate.
What if, rather than waiting for it to happen amidst fire and sword, we, as a country, decided to voluntarily split? Various Southern groups have pushed this for years, and #Calexit has been a thing since President Trump's election last November. The State of Jefferson has been proposed three times in three places over the years, while the tongue-in-cheek Conch Republic could probably get of the ground tomorrow. Many in Hawaii would like to return to the days of their independence.
I can keep this up for a while, but I hope you see my point. The melting pot that we were all told about in school (well, if you're of a certain age, anyway) may very well never have really existed. Like the nations that were press-ganged into the Soviet Union, there are a lot of groups and areas in the US that would quite happily take their 40 acres and a mule and bail.
Would half of the North American continent suddenly split up into 6 or 8 or 25 nations be a good thing? Would it encourage the remaining large nations such as China and Russia to indulge themselves in empire building? Would the newly independent nations find themselves forming a new Confederation in order to defend themselves from Mexico or Germany or Fiji? Would it be like Europe before the EU, with periods of peace and war?
We have no way to know. I suspect it would be a calmer version of the old Europe with some sort of alliance structure for defense from powers off the continent, but that's a guess.
What I hope it could be is the safety valve that we desperately need. With a number a new, English-speaking nations, hopefully with governments of widely varying stripes, all co-located on the same continent, people could find one that relatively well suited their particular wants and desires and immigrate to it. Some would complain that the new nations would be echo chambers, but so what? Most people prefer to live and associate with those who are like them and who share similar beliefs. Acknowledging that and allowing it to occur peacefully and without interference in another country won't hurt you in yours.
I don't think it's likely to happen, but it's a thought.
