Personally I can care less who South Korea elects as a leader. What I have a problem is the Chinese reaction to it. You know how terrorists win? It's when you're terrified. That's why they're terrorists. It's not the killing. It's the terror in the people who are still alive they use to get what they want. If you're terrorized, they have power over you.
Americans like to brag about their military prowess meaning they like to threaten it to countries that they don't like or do what they want. Just like a terrorist. I come across Americans that taunt destroying China because they think they have the power to do it. It's because they want to see and relish expecting Chinese to be terrified at US power. When they come across someone like me, I'll say, "Then why don't you do it right now? Is it because you're... chicken? If you have the power without fear of loss then why don't you do it?" Everyone one of them are shocked and say nothing afterwards because they were expecting terror, an admission to US power. Their arrogance instantly turns into pathetic self-defenselessness.
In the case with the South Korean election... of course they want to side with the US because it about expressing power over China. It doesn't help when Chinese express disappointment either. It's like when Beijing says something the US does hurts the Chinese people's feelings. Do they really think the US will accommodate and not do what "hurts the Chinese people's feelings?" No they will do it more because they know they have power over the Chinese because they know they can hurt Chinese. South Korea is nothing without the US and the Chinese do acknowledge the US is in a higher authority so it shouldn't be surprising which side South Korea is going to pick. Chinese expressing their disappointment only makes them feel better.
I was at a friend's party years ago. His daughter was being annoying with all the adults but the adults were being careful and played nice with her instead of being stern. Then she set her sights on me and started hitting me with a bean bag while I was talking to someone. She started hitting harder as I ignored her to the point where I took the bean bag from her. She was angry and told me, "I hate you!" And I said to her, "Good, I like it when you hate me." She started crying and walked away. She didn't expect that response. She was expecting me to be sad at her expressing that she hated me. Do I feel bad that I made a little girl cry? No not really because I didn't say anything to hurt her personally. She said she hated me and I was okay with it. That's how you have to treat the US, South Korea, or any other country that thinks they can feel good at China's expense. Every single one of them acts like a spoiled child thinking they can do anything they want to you but when you punish them for it, they start crying like a child. Look at the EU slapping sanctions on China over the fake Uighur genocide. And then China slapped their own sanctions back and the EU thought they were the ones that were being wronged. They were still supposed to make money off of China as if it was their right. No, it's China's right to deny them something that belongs to China just like they think they can deny China from making money from them. Only a spoiled child thinks it can have that kind of lop-sided relationship. Countries that have anti-China feelings in their population should be denied access to China especially those in Asia where China is their number one customer. Chinese expressing their disappointment is worthless. Some Chinese think that's taking the high road. No one recognizes China taking the high road. Action speaks louder than words.
