The Magnitsky Act says that Russian human rights violators will have their assets frozen in the West. It also says that beneficiaries of the $230 million crime will be sanctioned. That Putin was a human rights violator was not in dispute, but now he ticked both boxes. The Magnitsky Act put all of his wealth and power at risk. That made him a very angry man. His crusade against the Magnitsky Act wasn’t just philosophical, it was personal. We had genuinely hit Vladimir Putin’s Achilles’ heel.
