@pbsnews: The war in Ukraine has now officially lasted longer than World War I. As of Thursday, it's been more than four years and three months since Russian President Vladimir Putin sent troops into Ukraine. The conflict has drawn comparisons to World War I, especially the return of trench warfare, grinding artillery battles and front lines measured in yards rather than miles. Today, there is no end in sight to the present-day war.
