Now let us assume that the US and allies, Asian and EU, decides to help Taiwan ala Ukraine, meaning not troops but materiel DURING the war. So Taiwan inflict serious losses on the PLAN making the blockade weaker, then we resupply Taiwan defenses.
NATO is supplying real time intelligence, weapons, training, and men (maybe PMC, not official military) to Ukraine, but both Russia and NATO are playing this surreal game of pretending NATO isn't helping Ukraine because they want to avoid direct conflict.
This surreal denial won't be possible in Taiwan. To break through a PLAN blockade, US would have to directly engage with PLAN.
Will US officially declare war on China?
