Ukrainian soldiers on the front line doubt that peace talks can end the war with Russia. Explosions from Russian weapons keep them almost always underground, and nothing on the Eastern Front suggests an end is near. Soldiers' skepticism over diplomatic peace efforts is rooted in months of what they see as broken U.S. promises to end the war quickly. Suggestions to exchange territories confuse and frustrate them. Some soldiers believe a brief pause in hostilities is more likely than peace. As the war drags on, soldiers train intensively, knowing there's no way back.
