Question

Quizplus · Accepted Answer

The effectiveness of the alliance system in achieving security and encouraging negotiated solutions was a perceived benefit of the system, not an underlying reason for war. The other options - the arms race, deep antagonism between Germany and France, use of nationalist and militaristic foreign policies, and limits of the diplomatic system - all contributed to the tensions and ultimately the outbreak of war in 1914.
