Excuse my candor but isn’t the status of Taiwan way more contentious than Ukraine? Honestly I’m not the sure the claim is illegitimate enough to stop China (at least that’s what I get after just reading Wikipedia), so while unfortunate for Taiwan at least I hope public opinion in other countries might not want a war, given it’s not even recognized by a lot of countries. The strategic importance it has for the US (and Europe?) is problematic obviously though.
There's always the more modern and enlightened way of doing thing of having something like a Chinese Union like the European Union with free trade and the like but separate governments. I'm hoping the mess in Ukraine encourages the Chinese to look to more peaceful options.
