There are countermeasures for all contingencies. > you could bomb them with planes Not necessarily. If a plane has a combat radius of 600 miles and it can't take off from within 1000 miles of the theater, and it can't refuel once in the air, then it's tricky. Maybe the planes have very long range missiles, but those can be electronically jammed, and the targets are moving. The US has both refueling tankers and B2s that have a very long range. But refueling tankers are not stealthy, so China has a chance to take them down, and B2's are extraordinarily expensive. > you could torpedo them with submarines Once a submarine launches a torpedo, it ceases to be stealthy. Of course, it can regain its stealth mode if it submerges quickly and leaves the area, but it becomes a game of cat and mouse. It's possible for China to infest the area with lots of unmanned underwater vehicles that could patrol and once an enemy submarine is identify, keep track of it. > you could mine the area where they land There are ways to get rid of the mines. Lots of ways. Plus, if China feigns an invasion and doesn't actually invade, what is Taiwan to do? Leave the mines there? Permanently? That is quite hazardous for the civilian population. If China feigns 4 times and attacks for good the 5th time, will this be a problem? Bottom line: these questions that you are asking and I am answering: there are a few thousand people in China that are asking the same questions and trying to come up with answers, and then some are wargaming the answers and some are trying to come up with answers to the answers to the answers. There are people in the US who do the same. But China's threat to invade Taiwan should not be taken lightly.
