Assessing the aftermath of Russia's failed winter offensive in Ukraine.

Russia's winter offensive in Ukraine has failed to deliver gains, with both armies deadlocked and troops stretched across the region. The battle for Bakhmut has become the longest and bloodiest in Ukraine, with little strategic value. The Russian army lacks trained men and has artillery ammunition supply problems. The war has decimated forces and drained resources on both sides for more than a year. Ukraine has access to Western intelligence, training, and weapons, prolonging the conflict. Russian President Vladimir Putin appears committed for the long haul, but no one understands how he could secure a victory.
