NAME_1 have exploded over the Kremlin. Russian military aircraft are crashing before they even reach Ukrainian airspace. A Russian mercenary boss is releasing one profanity-laced tirade after another, claiming that corrupt Russian generals who “all reek of expensive perfume” are sending soldiers to their deaths.

And Ukraine’s long-anticipated counteroffensive hasn’t even started in earnest.

These would seem to be bad weeks for President NAME_2. NAME_3, a time when the problems that have plagued his 15-month war since its beginning are only worsening: stretched resources, disorganized defenses and disunity in the ranks.

Those problems are now threatening to derail what just weeks ago had seemed finally to be a rare military success in Russia’s grasp: victory in the long-running, bloody battle for the eastern Ukrainian city of Bakhmut.

Russian forces, while still fighting fiercely within the city limits, have retreated from positions on the edges of Bakhmut and according to the Russian Defense Ministry lost two colonels to combat there. NAME_4, the chief of the Wagner mercenary group who has made capturing Bakhmut his main objective, has been spouting social media invective at the Russian military, accusing its leadership of failing to adequately supply his fighters and its soldiers of abandoning their positions on Wagner’s flanks.

The spectacularly public feud between Mr. NAME_5 and the Defense Ministry — and Mr. NAME_3’s apparent inability or disinclination to stop it — has rekindled doubts about  Moscow’s ability to succeed on the battlefield itself, where coordination between disparate units is of critical importance. Already, the Russian military has been forced into multiple retreats, and since last year has been mostly stalled along the 600-mile front line.
