As reported by Censor.NET, this was announced by the White House spokesperson Josh Earnest.
"There have been serious doubts that have been raised about Russia's credibility, and Secretary Kerry's statement today indicated that it's difficult to engage diplomatically with the Russians when they're not living up the commitments that they have made in the context of previous diplomatic discussions. That's a rather obvious observation, but when you see the actions that they have undertaken or supported over the last couple of weeks, it raises serious doubts about whether Russia has a strategy that serves their national interest.
"Right now, they appear to be pursuing a set of tactics that worsens the situation in Syria, that deepens the humanitarian tragedy that's taking place in Syria, but also that increases the risk that Russia is exposed to. Russia is deepening their involvement in a sectarian conflict. Deepening their involvement in that quagmire is not going to be in the interests of their national security.
"And our hope was that, through diplomacy, we would be able to help Russia chart a path out of that quandary and in the direction of working effectively with the United States and our coalition partners to confront challenges in a way that would benefit the broader international community. But we haven't seen that kind of cooperation from the Russians, and it's taken a significant toll on their international credibility," Earnest said.
