What Taiwan needs is a dozen short to intermediate range nuclear tipped ballistic missiles. That would be a deterrent that Communist China would have to consider.
Amen to that brother. If or when the mainland begins their assault on what they believe is a rogue break away island, it'll be brutal. Taiwan doesn't stand a chance. Not even a small chance. They will fall very quickly.
China has thousands of surface to surface missiles all along their coastline aimed toward Taiwan. The first assault will take out infrastructure, military installations, naval assets. Then thousands of Chi-com troops will pour on to the island from across the straight.
Hate to put it like this, but it's just a simple truth. I work with many Taiwanese and have over the last couple of decades. They don't have the backbone to defend their nation. In fact, we'd go to lunch with them and I just cannot help but ask about this subject and their declaration of Independence...or lack of it and they bow their heads and say, “we do not discuss such things”. Almost all of them avoid it.
