Thank you so much for the complement, and for being so civil!
I agree with you that the historical plausibility, however far abstracted, is where much of the game's appeal comes from. I disagree with the characterization that the global happiness mechanic is historically implausible, but maybe you are more of a historian than I? In any case, I think we can also agree that it is not the most historically implausible aspect of the game! Maybe not even in the top ten? I am sorry that you find it immersion breaking.
There are plenty of war games, and even a few simulations, that don't incorporate anything like war weariness. I would remind you that the civ series has always (well, at least since II) had some game mechanic that worked against rampant war mongering. There has also always been a happiness mechanic as growth limiter and as main component to balance the difficulty settings. I feel like the global happiness metric is more integrated, more elegant, and less gamey, than what we have had before. YMMV
