The USA of course. Isn't it obvious? What other country is more Free and great? None. Why does this even need to be asked?
China is full of people who want communism to dominate the world with totalitarian control so no one wants China to dominate anything at all because they are bad...
The USA is being led by a criminal pedo atm. There is military in the streets and SA-like, masked thugs are kidnapping people. Billionaires sit behind the wheels to profit from all those developments. Many of them are somehow related to AI. You can image what that will be/is used (see Palantir).
The whole country is going down the drain right now. There is nothing about it, sane people outside the Republican bubble would consider "freedom".
I chose to believe that too until Trump got elected for the first time.
Now I just assume, a significant amount of US citizens have lost their minds and since this part tends to be quite loud about their madness, chances are much higher if you assume madness first.
