Yep. They want to enjoy the benefits of the collaborative effort. They are capable of maintaining their own separate network, but instead they chose to connect and put a ton of resources into managing the internet activities of their citizens. Knowledge of how to bypass those restrictions is apparently pretty widespread though.
Interestingly, North Korea does maintain it's own separate, fake internet. They manually copy approved sites over from the real internet, and heavily monitor usage.
Nah. The US hasn't been able to force Russia to stop their invasion of Ukraine, nor stop them from playing fuck-fuck games all over the rest of the world. And China is almost certainly stronger than Russia is. They both joined the internet because they wanted to, not because they were forced.
Oh, they'll just choose to cooperate and act like a single central authority? Without a preexisting central authority forcing them to? ๐ค
