Politkovskaya, Litvinenko, Magnitsky, Nemtsov, Navalny are only some of the most well-known names on the long list of critics killed by Putin.
There was outrage after each murder, but Putin eventually got away with it, and world leaders shook his hand again. This encouraged him to continue killing people.
Today, some voices continue to call for Putin to be heard and negotiated with. It is time to end the naiveté. Before any meaningful engagement with Moscow can begin, Russia must be defeated in Ukraine and Putin must finally learn a lesson.
