Where the Russian leadership is undoubtedly culpable is in allowing a culture of impunity around such violence. Sometimes those wielding the revolver or poison are jailed, but those who ordered killings are never found. The Kremlin is apt to dismiss attacks on its opponents as "provocations". Occasionally there are hints that present or former security agents — or local bosses such as the thuggish Chechen leadership — have taken matters into their own hands, hoping to "please" the president. Yet Putin could have made clear to all that such activities will not be tolerated.
Where evidence against state-linked figures seems overwhelming, the response is often a knowing smirk. Andrei Lugovoi, one of two men the UK charged with murdering ex-KGB officer Alexander Litvinenko in London in 2006 with polonium-210, became a Russian MP a year later. Putin gave him a medal (officially for parliamentary work) in 2015 even as Britain's Litvinenko Inquiry was hearing of the radioactive trail Lugovoi left behind in London. Military agents accused of poisoning Sergei and Yulia Skripal with a nerve agent in Salisbury gave a risible interview claiming to have flown in on a bleak February weekend to see the cathedral spire.
Foreign investors should not close their eyes. Some argue there are "worse" regimes, or that their money and technology can encourage change. Such assertions were more valid in Putin's first decade, when hope remained that his "managed" democracy might evolve in a more liberal direction. Instead, with the president in his third decade and cleared to rule until 2036, the system has become more darkly authoritarian.
Many countries now have "Magnitsky" laws permitting sanctions against human rights abusers that they should use against any officials implicated in an attack on Mr Navalny. Leaders such as France's Emmanuel Macron who have sought a "reset" with Russia should also be wary. Dialogue on issues such as nuclear arms is necessary. But anyone seeking to engage should have no illusions about the nature of the system Putin has created.
