It is the biggest crisis confronting Western Europe in 20 years - Ukraine could be just days away from losing a key part of its territory. Russia stands on one side of this conflict, the United States and the European Union on the other. Hardtalk speaks to Poland’s Foreign Minister, Radoslaw Sikorski. He helped negotiate a deal to halt the bloodshed in Kiev and now warns President Vladimir Putin if Russia does not de-escalate, the EU will impose sanctions. However, last time such a crisis erupted it was the West that blinked first. Why does he believe things will be different this time?(Photo: Polish Foreign Minister Radoslaw Sikorski speaks during a joint news conference with Secretary of State John Kerry, June, 2013.
