Today I learnt history about World War 1 and I have a question that has been bothering me.
According to what I have studied, the Triple Alliance (1882-1915) was an alliance between Germany, Austria-Hungary, and Italy. And the term of the alliance is that if Italy was attacked by a power, Austria-Hungary and Germany would assist her. And likewise, if Austria-Hungary and Germany were attacked, Italy would assist them too.
How did Italy cancel the "agreement" in the Triple Alliance? I meant there were "fights" and "agreements in advance". Why did not Italy and how did it have the right not to participate into the WWI?
