The most important reason militarism contributed to growing tensions in europe was because

growth of a country’s military became a competition.
countries were less likely to use diplomacy to solve conflict.
countries conscripted men from outside their own country.
some countries’ militaries remained small.

Good Morning!

Among the problems that militarism causes we can cite the idea that guns are the solution to any political impasse. Thus, any problem of frontier, territorial dispute or diplomatic discussion can lead (as it did in the last century) in armed conflicts. Countries were less likely to use diplomacy to solve conflict.
