I worry for China's next generation of leaders. Rash actions and arrogance will be the end of everything China's has gained. The Americans want another Cold War because they believe since they won the last one they can win another one. China knows this and so far hasn't played the game the Americans wants China to play. You move with irrationality and you end up like Russia.
Maybe if they started to hiring leading people as young and inexperienced as Joshua Wong, you can start to worry but given that China does have the ability to self reflect and does have systems in place to oust those who do not look out for Chinese interest, we shouldn’t worry that much on that part. Besides, if one should worry, they should worry about how on earth the USA could seriously consider a Cold War style war with China when the only reason they won is because the USA had a manufacturing base and they had China aligned with the west rather then Russia, both of which is not possible now. It’s like the old saying (or is it), ‘call an ambulance but NOT FOR ME’.
