"The global community was extremely complacent, and I see two reasons: hypocrisy, based on greed. People would make statements that they did not support Putin’s politics, and his oppression of the political opposition, and the wars that he started… But at the same time they would continue doing business with him. ... People underestimate how dangerous dictators are. In 2014, we spoke to the UK parliament, we spoke at the Senate in the US, we were asked by a lot of people how they should talk to Putin, how they should frame the conversation, and I always advised that they should be as strict as they could. You cannot play nice with Putin."
