I highly doubt it is a coincidence, the chances of such a coincidence is so mathematically small
If it was coincidental the Secret Service would draw their guns.
Maybe it's a foundation for a larger plan ...0.o
Break up China? Are you serious? Tibet is a small corner of a huge nation. Nobody wants to break up China. China doesn't want to break the US. The US is their biggest trading partner. A weak US economy doesn't help China. The biggest criminals in the world in since 1917 are the Russians anyway.
Coincidence? No, it's planned.
