The only thing bullies understand is force. China has been trying to bully the rest of Asia for decades, and it looks like some of its neighbors have finally decided to push back.
Bullying works so well inside China, the CCP can't understand why it isn't working against the rest of the world. The CCP has no friends and is making new enemies everywhere. The only rational explanation is the current CCP leadership is incompetent, but that is normal for communism.
