The Planet of the Apes Cartoon That Accused the USA of Nuclear War (1975)

Image
In the mid-1970s, at the height of Cold War unease, a Saturday morning cartoon quietly crossed a line most children’s programming never dared approach. The Planet of the Apes Cartoon That Accused the USA of Nuclear War (1975) - YouTube  “ Return to the Planet of the Apes ,” which aired briefly in 1975, transformed a franchise known for spectacle into a vehicle for political anxiety, embedding fears of nuclear war, militarism, and national guilt into animated form.  While marketed to kids, the series drew heavily from Pierre Boulle ’s original novel, presenting a technologically advanced Ape City , bleak ruins of New York, and unsettling storylines involving chemical weapons and mutated Under-dwellers who eerily chant “USA” from beneath the rubble.

John Ross: How to paint like a Somalian

Image
Welcome back to another tongue-in-cheek episode of How to Paint Like a Feminist, where the satire is thick and the brushstrokes are heavier than the policies behind them.  John Ross: How to paint like a Somalian Pull up a chair—yes, even that big red one resurrected by presidential approval—because today’s palette tells a familiar story: Somalia purple, hemp green, and a shade that’s supposed to be red but somehow ends up pink, which, frankly, fits the theme perfectly.  As the hemp green gets smeared across the canvas like a wintertime mess you’d rather avoid stepping in, it becomes a metaphor for the latest continuing resolution being sold as fiscal responsibility under the new Trump administration, despite quietly carrying over Biden-era spending levels unchanged. Buried inside that same bill is a conveniently overlooked hemp ban, wiping out a $29 billion industry the government itself created just a few years ago—proof that what the government gives, it can just as easily t...
