It didn't have to be this hard. After days of negotiations, pro-Russian rebels in Ukraine holding victims' bodies and the flight recorder boxes from Malaysia Airlines Flight 17 agreed Monday to hand them over to investigators. While handing over the black boxes, separatist leader Alexander Borodai denied involvement in the crash, saying, "The Ukrainians had the technical capabilities and the motives to do it." On Monday, President Obama pushed for the separatists to end delays in recovering the 298 victims, and said Russia would "further isolate itself" if it didn't intervene. Russia's President Putin assured in a statement that the international experts would have secure access to the crash site. The bodies will be taken by train to a Ukrainian-held city where they will be given to the Netherlands.
