I hope the Iran war disaster for US does not lead to hubris in China regarding Taiwan war, but horror and recalibration.
Cause Taiwan can also play the drone, missile, underground tunnel game against China and China's current stockpile of planes, drones, missiles are just not enough to fight a massive war against Taiwan. They need more budget and start to invest in missile defense and mass drone defense. They need much more force mass rather than just focus on quality.
Huge challenge for China to solve the drone issue cause it makes defense so much easier and attacking so much harder.
So far the only solution I have seen is mass, flood the theater with more planes, more drones, more missiles than the enemy.
