The signs are abundant of how Ukraine frustrated Vladimir Putin’s hopes for a swift victory, and how Russia’s military proved far from ready for the fight.

A truck carrying Russian troops crashes, its doors blew open by a rocket-propelled grenade. Foreign-supplied drones target Russian command posts. Orthodox priests in trailing vestments parade Ukraine’s blue and yellow flag in defiance of their Russian captors in the occupied city of Berdyansk.

Russia has lost hundreds of tanks, many left charred or abandoned along the roads, and its death toll is on a pace to outstrip that of the country’s previous military campaigns.

Yet more than three weeks into the war, with Putin’s initial aim of an easy regime change in Ukraine long gone, Russia’s military still has a strong hand. With their greater might and stockpile of city-flattening munitions, Russian forces can fight on for whatever the Russian president may plan next, whether leveraging a negotiated settlement or brute destruction, military analysts warn.
