Look at Post WW II, Germany and Japan were completely destroyed, they reformed and came back at least for a while bigger and stronger.
Hopefully, we don’t go thru something like that, but in this day and age anything is possible.
I think our current constitution if followed would eliminate most of our problems, if get destroyed and come back should we adopt the same constitution, YES but with some tweaks.
Basic stuff like term limits on Congress, more teeth int he 10th amendment that would limit the Federal Government from so much control over our daily lives, sound money, elimination of the Federal Reserve, etc.
I’m a firm believer that the closer to the people the better the government, once you advance beyond the State Level Government, ultimately it turns out bad for everyone.
Mark Levin had a book that detailed a few amendments he’d suggest. All of your recommendations were in the book.
A few minor tweaks is all, mainly because the writers didn’t intend people to live so long so a lifetime appointment was usually under ten years.
Since we are playing make-believe as if laws could fix this....
The one thing that I think could be added to the constitution is the first proposed amendment (which was never ratified).
Look it up.
If you like government closer to the people, that’s your fix. Of course we are way past the point of fixing anything so as long as a proposed law would have a positive impact, it WOULD NEVER be enacted.
