How did allies win World War I?

Answer 1

The allies won World War 1 overcoming German aggression simply by tactics and strength of combined powers. The aggressive Germans were dreaming of conquering the whole world without assessing their own strength. The World World 1 which continued for 4 years was a big drain on their arsenals and financial power. So the exhausted Germans had no other alternative than to surrender before the allied powers. Thus the allies won the World War 1.
