You know it. 纪念诺曼底登陆七十周年 is very different the military parade in China. One is an just celebration of the past and the other is 秀肌肉 by displaying lots of military hardwars. That's why many countries don't feel comfortable by associating with China on this.
The Chinese are really THE master of manipulative politics. Military parade? fine, do it; but it is an event that will be over in a few hours; Only a country like China will spend years and many billions in preparation and play manipulative politics on attendance. It will be doing the same thing for Olympics.
