they don't even do that, they 'analyze' based on their impressions of China from 30+ years ago using the strategies most favorable to them. it's like them analyzing in 1970's how T-34s would do if they were lined up in neat rows in the open.Curiously, every western analysis of a Taiwan invasion I've seen is based upon the assumption that an invasion will take place with the forces available to the modern day PLA, instead of the available forces 5, 10, or 15 years on, when an invasion is realistic. Not to mention that China could easily ramp up military expenditures if a conflict is inevitable.
I haven't seen a single person talk about the impact of drones, SEAD capability or bunker busting SRBMs so already that's just shit.
