Why wasn't there a truce in 1915?

In 1915, there was no truce during World War I primarily due to the entrenched positions and ongoing military strategies of the warring nations. Both the Allies and Central Powers were focused on achieving decisive victories and were unwilling to halt hostilities that could undermine their military objectives. Additionally, previous attempts at ceasefires were often seen as tactical maneuvers rather than genuine peace efforts, leading to distrust between the parties. The war's escalating nature and the high stakes involved further diminished the chances for a truce.
