Poland’s foreign minister, Radoslaw “Radek” Sikorski, has been intimately involved in the Ukraine crisis, including in the negotiation of an agreement in February that then-Ukrainian President Viktor Yanukovych walked away from, further fueling the Maidan protest. Sikorski spoke with The Washington Post’s Lally Weymouth April 16, ahead of the diplomatic talks in Geneva aimed at defusing hostilities, about the crisis, U.S. global credibility and what Vladimir Putin has his eyes on next.
