2024 is definitely their window of opportunity, as it looks increasingly like Trump is going to clobber Biden.
Thus, if I were Taiwan, I’d be readying some of the most brutal and effective means of killing as many invaders as possible - such as being able to dump millions of barrels of oil into the water at the invasion beaches and lighting them on fire, multiple interlocking layers of fully automated, radar-controlled machine guns, minefields galore, and having an armed and trained populace with certain knowledge that any order from any government or military official to surrender is a false order (similar to Finland and Sweden). ALso, if they have the ability to take out the Three Gorges Dam with a large barrage of conventionally-armed rockets, that’d help a LOT. Make the Reds really consider postponing the invasion indefinitely - and definitely don’t depend on the Depends-wearing, lecherous old crook in Washington.
They own the ballot boxes Trump is clobbering no one. He clobbered them last time and see where we are? President is at Mar Lago and has to win a third time.
