All their evils are derivative of their religious fundamental: Only Jєωs are human.
From that single fundamental, they have developed an elaborate creed of malevolence, supremacism, and genocide.
Though their ongoing genocide in the Holy Land is one manifestation, World War I II III is the larger manifestation.
They believe that their moshiach will not come until all non-Jєωs are exterminated. They dress up the belief in Kabbalistic jargon of extinguishing "sparks," kelipot ("empty husks"), and Amalek, but, no matter how they dress it up, they want us dead.
