Unless you are talking of a first strike scenario,even ICBMs won't be of use for Taiwan given they have no strategic dept.They need the 8 subs Bush promised to try build for them-even a 300 mile cruise missile is very formidable on such a platform.
It's not IC, it is medium range BM. And the capacity to incinerate half of continental china on 10 minutes notice is precisely what i am talking about.
