The movie version of Wonder Woman made her debut during World War I, but in the realm of DC Comics, it was Diana's strange run-in with the Nazis behind World War II that proved the most memorable. Why? Because the villains were hell-bent on bringing down the United States... with milk.
Over the decades, Wonder Woman has seen no shortage of strange adventures, from crossing across the multiverse to fight the X-Men's Storm, and even losing the title of 'Wonder Woman' for losing a race through a meteor shower. But it was one of Diana Princes earliest adventures, 1942's Sensation Comics #7 that saw the Amazon foil the weirdest, or at the very least most convoluted plot to destroy America ever.
Passing a grieving mother on her way to work, Diana intervenes to offer assistance. She learns that the older woman's son had just died from being malnourished and that the woman's daughter is also knocking on death's door. Since she's a hero even out of costume, Diana offers to buy the grieving mother some milk for her and her daughter but is shocked at the price. "Twenty-Six cents a quart! Why, that's outrageous!" Diana exclaims to the store clerk. Wasting no time, she heads straight to the International Milk Company, which is apparently a thing, and barges into the president's office. The president stalls for a bit before dumping Prince down your traditional villain trap door, whereupon a pair of goons bring her to the company's plant.
Refusing to answer any of their questions, the henchmen decide to drown Diana - in milk, obviously - in the back of a tanker truck. Once sealed, Diana transforms into Wonder Woman and smashes a hole in the milk tank, leading the driver to stop to ponder why they're now being trailed by a stampede of cats. With the lasso of truth and some help from Steve Trevor, they deduce that Nazi spymaster Baroness Paula von Gunther is behind the plot.
In the hopes to draw the Baroness out, Wonder Woman somehow quickly organizes an enormous parade, hoisting a banner that "The International Milk Company is starving America's Children!!" The plan works, and soon after she's apprehended by the Baroness' henchmen and tied to a train tank car (again filled with milk), that's set to be rolled downhill into a pile of explosives. But first, the Baroness starts her requisite villain monologue and explains how the ultimate plan was to raise prices to deprive American children of milk, explaining, "Your rising generation will be weakened and dwarfed! Germany, in twenty years, will conquer your milk-starved youths and will rule America!"
Easily breaking free of her restraints, Wonder Woman throws a tree on the tracks to stop the train and, along with Steve Trevor, defeat von Gunther's thugs and bring the gangleader into custody. The two final panels see Wonder Woman (now back in disguise as Diana Prince) reading a newspaper about the hero's exploits and resenting the fact that the attention isn't being lavished on her directly. And in the final panel, which could make one think maybe this entire issue was a plot by the International Milk Company, sees Prince - as WW again- cradling babies and declaring milk to be, "the perfect food! Strong, healthy children today means a safe, happy America tomorrow."
So while the cover of Captain America's almost contemporaneous first issue sees him belting Hitler in the face, Sensation Comics #7 gives fans Wonder Woman fighting the good fight at home. For America. And for calcium!
