Vladimir Putin's war against Ukraine has cost hundreds of thousands of lives and is fundamentally an attack on democracy. Under international law, the invasion of a United Nations member state which poses no imminent threat to the invader amounts to the serious crime of aggression. But can Putin be prosecuted? And if so, will he ever be held to account?

This remarkable book, by one of the world's most celebrated human rights lawyers, shows how the Nuremberg trials of Nazi leaders validate the prosecution of Putin. Ironically, Putin's defence hinges on a doctrine invented by George W. Bush to justify his invasion of Iraq, which Geoffrey Robertson exposes as contravening international law. If Putin fails to attend court, Robertson argues that he could be tried fairly in his absence, ensuring a verdict that will give pause to China and other countries which look to destroy democracy.

This brilliant deep dive into international law offers a unique perspective on an unjust war, highlighting why democracy is not safe unless Putin can be put - at least metaphorically - behind bars.
