Aleksei Navalny dies but what can western leaders do but wring their hands?

Everyone has pointed the finger at Vladimir Putin for the sudden death of Aleksei Navalny, the one man with the courage to take on the Russian leader. He was poisoned with novichock by assassins while on board a commercial aircraft but miraculously survived. But as soon as he returned to Russia he was arrested and has been in prison ever since. He died in the bleakest of prisons in Siberia at the age of 47. He would never have been released, so he would have died in prison anyway. But at this young age? His death is both a tragedy and an outrage. But pointing the finger at Putin will get nowhere. Western leaders, from Joe Biden to Emmanuel Macron, have denounced Putin but all the talk of making the Russian president pay for the death is a pretty empty threat. Russia is aready awash with western sanctions because of the invasion of Ukraine. Another sanction or two will make no difference. So there will be a lot of wringing of hands but little else. The only hope would be if the Russian people protested in their hundreds of thousands but that's against the law in their country, so it would only lead to police suppression. Navalny has died but Putin will survive and will outlast all the western leaders who are now crying out for revenge. This is the real world we live in.
