Will countries around the world actually have the balls to do something about it if it does happen?
You mean the west, most countries in this world give as much attention to this as the world gives to them.
Today, anybody can say anything! China denied it, but if the US wants to save at least of its credibility, it needs to provide something concrete - words are cheap!
The US gained a ton of credibility during this war. I'm not sure what you're talking about. The whole process of announcing all the intel of the war coming to everyone before it began and announcing false flags before they happened worked wonders for US credibility.
Really? With the biolabs?
That's Russian propaganda that no one believes.
Well, keep drinking the Kool-Aid...
Seems like everyone is committing credibility suicide these days.
What are you talking about? Didn’t the US and numerous European countries just call out this entire Russian invasion before it happened?
Have you heard the term "self-fulfilling prophecy"?
