To make sure I get both questions in, and fulsome answers, I'm going to ask both at once.
Earlier today, the PLA conducted large-scale live-fire exercises on its island closest to Taiwan, which is only 66 miles away. How will Taiwan actually know when the first real shot in a conflict is fired? That's question number one.
The west has underestimated the PLA's technological progress in the past, and so we expect a war by 2027. In your estimation, can an armed invasion of Taiwan happen sooner than that?
