Now, why would an adversary do that ie give up their advantage? If the goal is global conquest, and only the West presents any real obstacle to that end, then identifying their designed destruction of certain foundational culturally cohesive elements will not elicit any respect. Rather, it will simply result in (a) duh; and (b) so?
Secondly, politicians and others practiced in the dark arts of power and control aren't that smart. Clever & cunning, yes of course; but smart? No. That is, they don't follow technology, so they always miss the big seminal change events. Good example: neither JP nor D were anywhere towards developing nukes in WWII - it literally came out of right field.
So too these mad attempts at re-making man to create a new serf class beholden to dear leader(s). But a funny thing happened on the way to the forum: DNA engineering, in the form of applied genetic improvements. First up, cosmetic enhancements ie hair, eye, skin tone, color and texture. Wanna guess what universal standard of beauty will be pursued when facial/body alteration becomes possible? What then of intentional social discord and interest group (faction) leverage? Poof.
The future isn't diversity, it's uniformity. No one really wants to be different and/or low status. Everyone seeks the same thing: mate selection, desirability, economic comfort - resentment and appeals to group ID result from failures to achieve. Genetically even the playing field, and who will have time for marching & complaining? What then of politicians playing the margins?
