The man facing down Putin's aggression as secretary of the Ukrainian National Security and Defence Council is Andriy Parubiy. He oversees national security for the nation having previously served as security commandant during the anti-government protests in Kiev.
Parubiy was the founder of the Social National Party of Ukraine, a fascist party styled on Hitler's Nazis, with membership restricted to ethnic Ukrainians.
The Social National Party would go on to become Svoboda, the far-right nationalist party whose leader Oleh Tyahnybok was one of the three most high profile leaders of the Euromaidan protests - negotiating directly with the Yanukovych regime.
Overseeing the armed forces alongside Parubiy as the Deputy Secretary of National Security is Dmytro Yarosh, the leader of the Right Sector - a group of hardline nationalist streetfighters, who previously boasted they were ready for armed struggle to free Ukraine.
