My point is exactly that you don’t enter a war to lose. If you enter a war and your problems cause you to not win then you have lost. This could be due to lack of military power, lack of stamina, political support, financial or whatever.Yes the Chinese will be more willing to lose civilians and as a party they can do as they wish, something that the west can't do.
However in military terms only ,there is not a chance in hell for the Chinese military to win.
By saying 'how many years 19?' you are claiming that it was the military alone that couldn't win and ignoring the social/political fallout.
Again, read some literature on the subject.
What we do know is that they went to defeat communism and they didn’t succeed in doing so and that to me constitutes a loss even though they were obviously superior militarily.
