You keep trying to dance around the issue of how much the US projects their power across the entire world. Imagine if the headline was "China upgrades military command in Cuba, warns of US threats".
Your reading comprehension is poor. I made zero point about US power. You keep deflecting the issue of your basic error and minimizing the Chinese aggression against its neighbors. Issue is Chinese expansion and aggression in South China Sea, in the straits of Taiwan and Sea of Japan, and how it's neighbors are now banding together to prepare for this aggression. Your masters the Chinese are dumb because by making threatening gestures towards its neighbors it's brought this all on to themselves. They really haven't been smart, if you can think about. But you are a low level worker at a troll farm, and incapable of thinking.
If US is being serious, it should establish a military base in Taiwan – unless US just treat TW as the next Ukraine.
Note the fact that US never grant TW statehood nor independence. Taiwan is the only pitiful political entity in first island chain that has no US military base, the cost of which TW will be happily to pay.
TW has been buying US weaponry since WWII. But most purchases delayed, outdated or undelivered.
