The time to increase support for Taiwan was yesterday. China's increasingly aggressive posturing and lack of communication with US military officials are concerning, and Washington — seeking to maintain peace in the Taiwan strait — is right to stand up to Beijing's hegemony.
Every economic, political, and military move the US makes in the Asia-Pacific region is calculated toward the goal of dominating China and the world. The Pentagon doesn't deploy troops and establish military bases to "defend democracy" but rather to scare China into submission. By antagonizing the superpower of the East, the US is asking to go to war over nothing but greed.
There's a 5% chance that China will recognize the sovereignty of Taiwan by 2050, according to the Metaculus prediction community.
