Clearly Russia's military prowess is respected. And the Russians clearly DO deserve it: how many NATO troops are officially fighting Russia in Ukraine? As far as I know, none whatsoever.Most people don't know the details of how strong various militaries are. They only know about recent wars. The Soviet Union was respected because of the second world war and Russia has inherited that respect. But they clearly don't deserve it. Vietnam earned respect through its successful defence against France and the US, but it wouldn't be very accurate to describe Vietnam's armed forces today as particularly powerful in the region. Reputation like this can be powerful, but it's only based on history, not today's facts. And you can only change it by fighting a war. Let's hope China won't need to fight a war to conquer Taiwan
China has already fought the US in the Korean War, and probably considers it unnecessary to fight the hegemon again. It's to China's great geopolitical advantage to be seen as a purely defensive power, as a power that does not assault its neighboring countries. (Taiwan is not a country.) In the long run, a pure defensive posture is a winning strategy for the Middle Kingdom.
