Oxnalia

A powerful, militaristic nation ruled by the evil dictator Razkal, who bears a strong resemblance to Adolf Hitler. When Oxnalia invades the peace-loving democratic country of Numark in March-April 1942, Superman single-handedly demolishes the Oxnalian war machine and forces its soldiers to sue for peace. Razkal attempts to flee by motorcycle, only to be shot and killed by one of his own countrymen (S No.15/3: "Superman in Oxnalia!").
