We couldn’t even do it right in Venezuela - how could we persuade the far more intelligent Hong Kongers to act up if they were unwilling?
While it is possible, I would hope we aren’t seeding this.
There really isn’t anything in it for us to get the population of Hong Kong to wave US flags of anything but their own volition.
I suspect China has no choice but to say this politically and the flags are likely entirely organic from the population. They are a very effective statement of “we believe in freedom” without having to use so many words.
Clearly it isn’t a whole lot more than that from our perspective. We are not going to invade China, or try to take over Hong Kong even if the population wanted it there is nothing we can or should do on that front. It’s a statement, nothing more.
A statement that CHINA should change.
China holds the world record for mass murder, so their assertions of truth are suspect.
The existence of the United States is a threat to tyranny everywhere. This has been true since 1789.
