No development during Vladimir Putin¡¯s 23 years in power has so clearly pointed to his regime¡¯s fragility as the Wagner Group¡¯s aborted mutiny late last month.

The Wagner mercenaries, led by Yevgeny Prigozhin, brazenly challenged the Kremlin¡¯s authority ¡ª and now appear to have gotten away with it. Russia¡¯s internal security service, the FSB, has its criminal investigation into the revolt. But Putin¡¯s problems hardly end with Wagner.

Prigozhin¡¯s fighters would not have been able to travel almost 1,000 kilometers (621 miles) within Russian territory in less than a day without help from members of Putin¡¯s inner circle or the military. Rumors are swirling that the billionaire brothers Yuri and Mikhail Kovalchuk may have played a role. The Kovalchuks, close associates of Putin, reportedly share Prigozhin¡¯s belief that Russia has not been forceful enough in the war or in its broader confrontation with the West.
