Italy entered the second world war in circumstances very similar to those in which it signed up for the first. Its leaders waited for nine months after the outbreak until they thought they had identified the winner and extracted promises of territorial rewards. In 1915 they guessed rightly and attacked Austria, their formal ally for the past 33 years, and they seemed to have chosen correctly again in June 1940, when France was already beaten and the British had evacuated Dunkirk.
