Good little article on the phrase origin here. Excerpt from the quoted 1838 editorial:
Ensconced in his mail of proof—for defence purely, his disposition being no ways bellicose—he snugly nestleth in his mucid bed, revels in quiescent luxury, in the unctuous loam that surroundeth him, or, with slow and dignified motion, worketh nearer the surface, as the summer suns warm the roof of his mud-palace, or sinketh deeper within, from the nipping frosts of winter.
Eh? The OUN, under Bandera's leadership, repeatedly and actively sought to alliance Nazi Germany during WWII. They formed militias with the express intent of enacting pogroms against Jewish citizens. Their political agenda was absolutely a fascist one. Bandera collaborated with the Nazis directly near the end of the war to fight the Soviets (though he was between a rock and a hard place here, I admit).
