This year’s Yalta European Strategy (YES) conference, known as the Ukrainian Davos, did not disappoint. Held in Kyiv on Sept. 13-15, the meeting featured the obligatory celebrities and A-list dazzle. Bono turned up in purple-tinted glasses. Host Victor Pinchuk unveiled a silver spaceship-like creation by Japanese artist Marico Mori urging everyone to focus on the future. The American punk band Gogol Bordello was electric.
