In this Tuesday, June 2, 2015 photo a Ukrainian army officer stands by a train traveling from Ukraine to the rebel-held territory that his platoon had just stopped and forced to go back, in Orekhove, Ukraine. Ukraine’s richest man Rinat Akhmetov has been able to straddle the front line in eastern Ukraine, keeping the lights on and people clothed and fed in the rebel-held areas while powering Ukraine’s economy and pouring hundreds of millions in taxes into government coffers.
