Malaysia Flight 17 has to be the most cynical troll-job I've ever seen by a state.
Your men killed hundreds of civilians in a plane. Then you lie and claim that completely innocent parties killed those people. And then not only do you lie about it, but you lie in the most blatant, ridiculous, obvious ways. They would change their entire narrative every third day, distribute completely photoshopped pictures to the media one day and then offer a different explanation the next day. Putin knows it doesn't even matter, cause 60% of Russia and 20% of America just auto-believe whatever bullshyt comes out of his mouth.
