Either Russia or China was behind it. The complicit press is covering for their leader Obama.
Just like when Putin sent a 4th of July greeting to Obama that was leaked by the Obama administration to the press. I guess they wanted to show relations were improving. The thing that only received light coverage from the majority complicit liberal press is that on July 4th Russian sent nuclear capable long range bombers after the 4th of July wishes within miles of US air space forcing US fighter planes to scramble to intercept. Putin just gave a big fuck you to Obama.
