There’s no diplomatic solution if the US decides there’s none to be had and doesn’t even try. Diplomacy fails at times but putting in a serious effort to resolve conflicts peacefully is almost always preferable to the hardships of war. Even if you think the PRC is belligerent it’s worth actually trying.
That’s why Taiwanese people prefer maintaining the status quo. To them it seems like the best of the bad options available to them as long as they have no control over what the PRC or US does.
That’s not how methodology works. You can’t compare numbers from two institutions and assume they’re comparable because they sound the same. There are often many ways of measuring unemployment or joblessness. If we look at youths without jobs versus youth unemployments in the US, both statistics you can find from the BLS, you would see that those numbers are wildly different.
Again just look at the world bank data which is using standardized calculations.
