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 But most purchases delayed, outdated or undelivered.
