Surprise,surprise. China's crackdown in Hong Kong.
Now, we all looked on as the protesters shut down the place for months, and those among us who watch China wondered how long it would take for China to react. Indeed we wondered if democratic countries around the world would tolerate such action by protesters if it were happening in their countries for such a long time.
Maybe we agreed with the protesters, however we knew China would react eventually because they were loosing face and because eventually Hong Kong would be handed to them, they decided to act. They have taken the first step and they are not worried about world opinion. They are always thinking long term, they know that world opinion only lasts as long as a headline
