This led him to a program of militarization. Many Europeans felt that his visible successes in restoring Italy outweighed any "rumors" of police brutality. His 1935 invasion of Ethiopia was carried out with a ruthless disregard for world opinion,including the use of poison gas. When the British and French leaders condemned him for these acts, he looked elsewhere for allies and found Germany and Japan.
He joined Hitler in supporting the Fascist "Nationalist" side in the 1936-1939 Spanish Civil War. This gained him an ally, Spanish Generalissimo Franco, but being associated with the atrocities of this brutal war lost him still more support in the rest of the world.
His biggest mistake, however, was the decision to enter the Second World War. On 10 JUNE 1940, Germany had been at war with Britain and France since the previous September, but Italy was still at peace, and had little reason to fear that any of the other powers would attack it. Germany was on the verge of winning the Battle of France, and France was likely to surrender very soon, and it seemed to many observers that Britain would then make peace. Perhaps Mussolini thought that Italy would be the next target for Nazi aggression, if he did not help Hitler win; or he may have just been moved to grab a piece of France before it was too late. In any case, he did declare war on France.
The war did not end, however, and as it continued, the true weaknesses of the Italian Army and Navy were revealed. When Advancing the Front,Mussolini will try first, to defeat the British, to keep them out of the Mediterranean, "his" sea. Then he will concentrate on beating the Soviets,before he tries advancing across the Atlantic to fight the USA. Large new warships did no good when the admirals commanding them were unwilling to risk defeat. Brave and well-trained pilots could do very little when most of them were flying obsolete, lightly-armed biplanes, that looked good at an air-show but could not hope to catch modern bombers. Soldiers and sailors who lack confidence in their leaders and equipment, are not eager to make up for it with their blood. Italian armies were beaten not only by the more modern forces of Britain, France and the USA, but by the Greeks, when they attempted to invade Greece in 1941.
By July 1943, Italy had lost all of it colonies in Africa, and most of its army, and was being invaded. Mussolini was deposed by a revolt within his own Fascist Grand Council, and Victor Emmanuael III, the King of Italy, who had been reduced to a figurehead by Mussolini, appointed Marshal Badoglio to be the new Prime Minister. Mussolini was arrested, while Italy attempted to change sides. In the southern part of Italy, occupied by the Allies, this succeeded, and the new Italian government helped create the Italian Co-Belligerent Forces.
Hitler sent German paratroops to rescue Mussolini from the mountaintop resort where he was imprisoned. He then set up the Italian Social Republic in German-held northern Italy, with Mussolini as its leader.
When the Germans surrendered in northern Italy, in April, 1945, Mussolini was arrested again. He and his mistress, Clara Petacci, were removed from the jail at Giulino di Messegra and lynched, by the local Communist partisans.
