I don't think we will defend Taiwan. The only way we could is to throw a nuke or 50 at China to slow them down. And hope our missile defense is up and running. China has threathened us so many times with nukes it is unreal. Plus, we better say the heck to all these countries and get what satelites we have in space and man them nukes. Soon will be WW3. I hope our people has the stomach for it.
