If there is anything to learn from the current situation IMHO, it's that 1) the US needs a stronger constitution to prevent a take over, and 2) it needs a new election system to avoid binary elections, which lead to extreme policy turnover and candidate fatigue.

There's nothing wrong with writing a new constitution. France is at its 5th iteration, and some candidates propose a 6th republic, nothing dictates that you're supposed to get it right on the first try.

The U.S. is the world's oldest democracy. It is functioning just fine.

France has been toppled by internal revolutions and external enemies multiple times in the time that the U.S. has existed. It's not an example to aspire to.

The US has gone through a dozen constitutional crises in the past 2 months and you call that functioning "just fine"?

It’s looking less and less functioning and less and less like a democracy every day.

And give France a bit more credit; they were instrumental in the US’s own internal revolution against the British.
