end the spirit of militarism.

Explanation:

In the early 20th - century, European nations built up military forces, formed alliances, and expanded colonies to keep a balance of power among themselves. This was a way to ensure no single nation became too dominant. Conscription was a means to build forces, not the goal. They did not aim to end militarism but rather use it to their advantage, and they were not trying to force enemies to start wars as an over - arching goal.

Answer:

B. maintain a balance of power.
