Help due soon! Overall, what is happening in terms of military build-up in the years prior to WWI? How might that lead to the war beginning?

Between 1890 and 1913, the European powers at the time began building up in military power. This included the countries of Britain, France, Germany, Russia, and Austria-Hungary. The reason for the military buildup was primarily nationalism in which each country wanted to be "better" than the others.
