What were the short term reasons explaining why Italy was willing to go to war in 1914?
Italy went to war in 1915. Originally Italy was allied with Germany and the Austro-Hungarian Empire, but this was mainly out of fear of France. Once the war broke out Italian politicians began weighing the cost of a potential war (the headlines were full of the dreadful daily casualties and the incremental gains) versus the potential benefits, and they finally decided that they could gain significant territory on the Adriatic coast if they went to war with Austria. It was a bad miscalculation.
