Following Mussolini's / Hussein's infamous use of chemical weapons in his first military invasion of a foreign country as head of state, the acting world government was unable to penalize the fascist aggressor for this gross violation of international law largely because of opposition by the leader of the West.
Riding unchecked by international law, this savage warmonger marched onward in his quest for world domination to launch another war and quickly stumble into a series of humiliating military losses in both conflicts. Mussolini's / Hussein's consecutive defeats in his invasions of two far weaker nations vividly portrayed a laughable bid at world domination by a bumbling Caesar-pretender seemingly destined for a cataclysmic fall from power within the gathering storm of the imminent world war. Hitler had an epic relationship dominating a foreign dictator who was a rival-turned-ally, Benito Mussolini. Ironically, Mussolini rose to power and world fame over a decade before Hitler. Publicly overflowing with a globally ridiculed ambition to conquer the world and recreate the Roman Empire, Mussolini was also a fascist warmonger guilty of some of the most notorious war crimes of the 20th century before even entering the influence of Hitler. Most infamously, during his first military campaign as Italy's head of state Mussolini ordered one of the few post-WWI military campaigns that employed the large-scale use of chemical weapons, targeting both military personnel and civilians in Ethiopia. When the two future partners of fated mass destruction first met on the world stage as regional rivals, Mussolini an established world leader and Hitler an upstart dictator, their hostility towards each other's territorial expansion plans and claims as the rightful heir to the Roman Empire was quickly superceded by a mutual belligerency against the leading Western empire, Great Britain. By the time of the start of WWII, Hitler would tower above the WMD-using Mussolini as his era's god of war, empowered with the seemingly invincible Nazi war machine and threatening unprecedented mass destruction with the shadowy Nazi nuclear weapons program that was complemented with an unstoppable bomb delivery vehicle, the Nazi V-2 rocket, the world's first intercontinental ballistic missile. Bolstered with the forces of his now-junior partner in military world domination, Hitler was poised to defeat Great Britain and succeed in this Alexandrian quest.
In 1939, Hitler and Mussolini entered the war pact "The Pact of Steel" that would propel Mussolini into a regional war months later when Hitler invaded Poland in late 1939. This war pact would soon draw Mussolini into a world war in 1942 when his ally Hitler initiated a single war against Britain, Russia and America.
In 1943, this war quickly led to an overwhelming Anglo-American invasion that toppled Mussolini's brutal Italian regime, helped to capture and imprison the hated fascist tyrant, and in July of 1943 established a new provisional government to rule Italy that quickly acquired the backing of the United States.
The leadership of the military opposition to this occupying Anglo-American army was quickly usurped from Mussolini's faltering Italian army by Hitler's fearsome Nazi army. In a public reflection of this fateful end to their sea-saw relationship, during his imprisonment Mussolini served as a puppet leader for Hitler's propaganda war against the Anglo-American military occupation of Mussolini's country that Hitler had provoked.
The eventual grisly execution of Mussolini by a vengeful group of partisan victims of his criminal regime was a tribute to the brutal fascist reign immortalized in the infamously vindictive scene of his corpse hanging from an iron scaffold.
