Maybe. It’s a question of the price they’re willing to pay to do so. Between the aid we’ve provided until now, and whether or not we’d go to their aid if China ever attempts a military invasion…you’re not wrong that if China wanted it badly enough they could take the island.
But it would not be quick, easy, or cheap. Active US assistance to Taiwanese defenses would make everything that much more expensive to China.
That's exactly why we need to create economic separation between ourselves and Taiwan,.. Because when the smoke clears, China will be calling the shots on Taiwan...
