"Putin was telling us what he was. All we had to do was listen. When Putin said that there was no such thing as a former KGB agent, I knew Russia's fragile democracy was in danger. When Putin said that the collapse of the Soviet Union was the greatest geopolitical catastrophe of the 20th century, I knew Russia’s newly independent neighbors were at risk. And when Putin talked at the Munich Security Conference in 2007 about a return to spheres of influence, I knew he was ready to launch his plan. It was the language from the Molotov-Ribbentrop Pact, 1939. The language Hitler and Stalin used to divide Europe. And a year later, in 2008, Putin invaded the Republic of Georgia. 2014, Ukraine."
