Sagot :
Because industrialization lead to a work force which eventually turned into a militarism because the work force could now make their own amo and guns which they didn't have to rely on other countries
I believe the answer is: industrialization offered new methods of shipbuilding and the use of iron, steel, and chemicals for new weapons and growth of mass armies in europe
Because of industrialization, it is far easier for military department to obtain war weapons and vehicles on cheaper price and largest quantity. This lead to militarism which initially intended for national defense, but some countries such as Nazi germany used it for conquests.
