1. If countries become Permanent member based on "Potential" ...then why you are opposing the expansion of UNSC to include Germany, India and Japan?..they all have potential to become world powers.
2. Thant is your flawed theory....rest of the world believes it's a "Chinese" virus.....try hard and convince the world.
3. That's disputed...this is your version that Tibet has been part of China since Yuan Dynasty (13th century)...But Tibetan govt. in exile as well as western historian acknowledge that Tibet has been an independent state. In 1943, Chiang-Kai Shek claimed it as China's part and in 1957 you occupied it.
