To be fair, they did take on… the world.
Jojo Rabbit (2019)
Jojo Betzler: What’s going on out here?
Yorki: The Russians, Jojo. They’re coming. And the Americans from the other way. And England and China and Africa and India. The whole world is coming. Help me with this ammo.
Jojo Betzler: And how are we doing?
Yorki: Terribly. Our only friends are the Japanese. And just between you and me, they don’t look very Aryan.
You’d figure that would take about 5 seconds for the world to win, but weirdly, it was kinda close.
It wasn’t close. Plenty of countries hadn’t joined in yet. Only European countries and allies were fighting directly.
