It is the U.S. that is causing the crisis over Taiwan. Not that the U.S. is supporting Taiwan, but because the U.S. has been completely wishy-washy over Taiwan's status.
- Taiwan is an independent country and needs to be fully supported and defended completely. Or,
- Taiwan is a part of China, the U.S. needs to acknowledge that and get out, as China can do whatever it wants with its own territory including invade and suppress.
