But if they are playing long game that would not matter. Think how far the pendulum has swung since LBJ (never mind JFK who would be considered a racist conservative by today's standards). What is another 50 years? Nothing in the grand scheme.
No, I think the real problem with #1, #2 and #3 is who exactly would benefit from this. These imply a grand plan which requires a grand organization with good leadership ability to keep the plan on track to reap the promised rewards. I see no evidence of such grand leadership and or organization. I see chaos where one would expect control.
So that brings me back to #4 as more probable.
Again I not saying it is the answer, only that the probability of it being right is better than #1, #2 and #3.
In that sense of historical time, I think you are right. Hard for people to fathom that just 70 years ago 70 million people world wide perished in WW2. And today it's mostly forgotten; and hardly ever talked about. Moreover look at just the last 5 1/2 years.
Even despite the obvious failures of modern day liberalism and its policies; there are some very educated thinkers in that camp. And I am not talking about college academicians. Many of them are lost in that radical leftist horseshit from the 60's and 70's. I am talking about technological geniuses, and just great minds that can deduce cause and effect brilliantly. What don't they see (as extremely educated humans), that keeps them clinging to these failures along with these dummies. It makes no sense.
