So what, exactly, does Vladimir Putin want? ‘To start World War Three,’ according to the embattled Ukrainian prime minister Arseny Yatseniuk. ‘To rule as president for life with powers on par with the tsars,’ according to Alexei Navalny, leader of Russia’s tiny opposition. To ‘force a major change of boundaries on Europe… and break the post-Cold War consensus,’ according to Radek Sikorski, Poland’s foreign minister.
