To me, the Taiwanese people have already silently made that choice of independence. Even if independence isn’t loudly proclaimed, Taiwan is still silently at war with China. Otherwise why spend so much money on war equipment from the US, and why have mandatory military service?
To me, the rest of the world powers, the G7, can jointly recognize Taiwan. At that point China will loudly complain and declare hurt feelings, but they will back off. Because there will be nothing they can do unless they want to become the world enemy.
