We got a taste of what a real “armed insurrection” looks like this weekend. No Viking garb or selfie-taking grandmas in sight. And it had the world on edge.

The Russian mercenary force Wagner Group, a potent weapon in Vladimir Putin’s war against Ukraine, suddenly turned on Putin this Friday. Led by Yevgeny Prigozhin, the Wagner Group crossed into Russia, taking crucial military sites, taking down Russian helicopters, and began advancing toward Moscow. The military prepared to block the rebellion. There were even reports Putin had fled the capital.

The move was called the greatest threat to Putin since he took power.
