BTW why don't the US publish their evidence as well as Russia did? They presented to the world community satellite shots with suspicious movement of Ukrainian air defense systems and a warplane, and America keeps on telling that it's Russia propaganda. However, Russian Ministry of Defense told they are ready to submit these materials to any international body for an expertise. Seems that Obama is losing.
Because they understand that now they're responsible for everything what happened since installation of coup government in Kiev. It even doesn't matter who have shot down this plane, that wouldn't happen without their "investment into ukrainian democracy". All that remains is fill the media by the meaningless statements, pretending that they have some kind of value.
