Indoctrination has always been fairly solid in the US through the public schools systems, its only natural the budgets continue to increase and they get better and better at it.

As a elementary school kid in the late 80's early 90's our school had everything from guest speaks, to posters, to t-shirts for everything from:

-hold in the o-zone layer -D.A.R.E. -AIDs -nuclear bomb test drills

It seemed one day over night the O-zone layer posters went away and now it was global warming. And sure all of that may make sense in terms of maybe a science class, but this was more of a general lets not teach and indoctrinate. Plus the AIDs stuff always seemed weird, teaching about sex/needles to kids as young as 6. I wouldn't be surprised if that all went away as well for the new topic de jure. I think DARE was also finally pulled from schools and had all kinds of other scandals surrounding the programs that were exposed.
