Russia's initial offensive failed

 ISW:

Ukrainian forces have defeated the initial Russian campaign of this war. That campaign aimed to conduct airborne and mechanized operations to seize Kyiv, Kharkiv, Odesa, and other major Ukrainian cities to force a change of government in Ukraine. That campaign has culminated. Russian forces continue to make limited advances in some parts of the theater but are very unlikely to be able to seize their objectives in this way. The doctrinally sound Russian response to this situation would be to end this campaign, accept a possibly lengthy operational pause, develop the plan for a new campaign, build up resources for that new campaign, and launch it when the resources and other conditions are ready. The Russian military has not yet adopted this approach. It is instead continuing to feed small collections of reinforcements into an ongoing effort to keep the current campaign alive. We assess that that effort will fail.

The ultimate fall of Mariupol is increasingly unlikely to free up enough Russian combat power to change the outcome of the initial campaign dramatically. Russian forces concentrated considerable combat power around Mariupol drawn from the 8th Combined Arms Army to the east and from the group of Russian forces in Crimea to the west. Had the Russians taken Mariupol quickly or with relatively few losses they would likely have been able to move enough combat power west toward Zaporizhiya and Dnipro to threaten those cities. The protracted siege of Mariupol is seriously weakening Russian forces on that axis, however. The confirmed death of the commander of the Russian 150th Motorized Rifle Division likely indicates the scale of the damage Ukrainian defenders are inflicting on those formations. The block-by-block fighting in Mariupol itself is costing the Russian military time, initiative, and combat power. If and when Mariupol ultimately falls the Russian forces now besieging it may not be strong enough to change the course of the campaign dramatically by attacking to the west.

Russian forces in the south appear to be focusing on a drive toward Kryvyi Rih, presumably to isolate and then take Zaporizhiya and Dnipro from the west but are unlikely to secure any of those cities in the coming weeks if at all. Kryvyi Rih is a city of more than 600,000 and heavily fortified according to the head of its military administration. Zaporizhiya and Dnipro are also large. The Russian military has been struggling to take Mariupol, smaller than any of them, since the start of the war with more combat power than it is currently pushing toward Kryvyi Rih. The Russian advance on that axis is thus likely to bog down as all other Russian advances on major cities have done.

The Russian military continues to commit small groups of reinforcements to localized fighting rather than concentrating them to launch new large-scale operations....

The culmination of the initial Russian campaign is creating conditions of stalemate throughout most of Ukraine. Russian forces are digging in around the periphery of Kyiv and elsewhere, attempting to consolidate political control over areas they currently occupy, resupplying and attempting to reinforce units in static positions, and generally beginning to set conditions to hold in approximately their current forward positions for an indefinite time. Maxar imagery of Russian forces digging trenches and revetments in Kyiv Oblast over the past several days supports this assessment.[1] Comments by Duma members about forcing Ukraine to surrender by exhaustion in May could reflect a revised Russian approach to ending this conflict on terms favorable to Moscow.

The digging in of the Russian forces suggests a siege strategy with continued bombardments of civilian targets.  The media should rightly condemn the war crimes and the Russian strategy and tactics.  Putin probably does not care, but it makes sense to prepare for the post-war and give the demoralized Russian troops another reason to question the illegal orders.

It is hard to justify the use of the hypersonic weapon against Ukraine.  It is like a losing fighter flexing his muscles.  It does nothing to change the battlefield that ordinary munitions can't do.

Russia's inadequate force to space ratio makes it unlikely it can recover the initiative at this point.  Hammering civilian targets with munitions will likely have negative ramifications for the Russian operations and complicate the postwar period.
