I said what will be the sane thing to do. S400 can be deployed in the high altitudes. Its not that it won't work just that the terrain will provide enough shadow areas for fighters to hide and ultimately operate in blind spots, that's true for both sides. Please try coming up with your own arguments, media reports are a dime a dozen, not worth the paper (data space) they are written on.
Security basics, never leave fronts open, always maintain war reserves in all theaters of combat or possible combat. War causes attrition of men and material, both. Also you are reading stuff not being written I didn't bank on the goodwill of PRC, I said if they decide to throw everything at us that will be stupidity, no one does that. Weapons have lead times in production and in deployment, Man power training mobilization . I am not banking on Japan and USA, I am saying that they are always a threat to CCP, theyll leave other avenues open if they are sure US wont do anything, is being too naive, they cant leave the Main land unprotected. If they do... good on them. CCP Political leaders will be too easy a target even for dissenters.
Learning to fly a bird and having them war ready and integrated to the overall force structure are two different things. Even wars have thresholds, in convention. The side going in all bell and whistles from the get go, are playing too much COD. War is serious business, and as messy as it meets the eye... it is as skillful as surgeon in works, hence the word "Operation". Tools are employed to meet tactical objectives.. all aligned to meet a common Goal.
I don't comment on individual opinion and activities, ex Officers are free to say whatever they like, they have their own code of conduct and I'll leave it at that. Propaganda was winning Egypt in the 6 day war and Pakistan in 1971. In a conflict scenario all information is disinformation, believe only what you can independently verify.
