Sigh. Hopefully we won't get a repeat of the Tiananmen square massacre. I've not seen any nations speak out about the HK protests. Unlike, say, when many expressed support for the Arab Spring.
To pretend like it was a moral issue is insane. Most people don't care in the slightest in democratic countries. Virtually every country involved in sending troops couldn't point to it on a map nor talk about the region with any sort of knowledge. We walked in and replaced Hussein with ISIS. It will go down as 21st century Vietnam.
China has nukes. Absolutely nothing will happen regardless, just like 30 years ago. Perhaps some more outrage on twitter I guess?
