I ain't gonna lie I had no idea Russia would have such a hard time with Ukraine whenever you come up with ww3 scenarios it'
USA
China
Russia
now I'm wondering if China could even take Taiwan if they wanted to
Nukes are such a threat I think many countries let readiness fall by the wayside. Russia proving itself a paper tiger, China I don't know, but they haven't fought a WAR in ages.
The difference between the US and many of these countries, is the difference in military readiness, infrastructure and advancement (technology).
China, unlike Russia, has the tech and natural resources to maintain it's fighting force. Now their question is all about readiness and will to fight.
