The first Trump term and now the 2nd will push the US in a certain direction. Trump will not get too much credit from the historians. It will be noted that there was a shift. The voters are not happy and part of it is that the US Constitution is no longer working for us citizens the way it did in the 1900s, even through the Reagan years.
The result will be a US with a big army and some strength. But no longer keepin military bases all over the world and cruising air craft carriers. Those were around for the purpose of providing a base in a place where there was not a lot of US support. Middle East, Asia, Russian neighbors. Air craft carriers do not enter the Baltic as those are now all NATO countires. And they never did.
The other trend that we will see is that red states are on their own. The South will be poor. Even federal highway money will be less and less. The blue states will continue as they did. They produce a lot of income and will take care of their own. They will invent their own healthcare.
Healthcare will change. Traveling to a different state may require travel insuranc, in case you get sick. The states will become little coutries. Sharing only the millitary and the dollar. Federal spending will tighten and will run a lot like the EU. Some states will need to be bailed out from time to time. Catastrophies will need special laws for recovery, each one. Some kind of financial arrangements are made. Somehow the states will get independent economies. Don't ask how, I am not an economist.
