Kerry negotiated an agreement with Russia to share joint military operations, but it fell apart. "Unfortunately we had divisions within our own ranks that made the implementation of that extremely hard to accomplish,” Kerry said. “But I believe in it, I think it can work, could have worked." "It’s late now obviously because of what’s happened to Aleppo," he said. “But the fact is we had an agreement in which Russia gave us a veto over their flights and over what they were doing in the area, had we set up a joint cooperative effort." "Now we had people in our government who were bitterly opposed to doing that," he said. "I regret that. I think that was a mistake. I think you’d have a different situation there conceivably now if we’d been able to do that."».

At the same time, lower down the ranks, at the operations level, one of the American military service personnel said quite frankly that they spent several days preparing this strike. How could they make an error if they were several days in preparation?" said Putin. "This is how our ceasefire agreement ended up broken. Who broke the agreement? Was it us? No." Several western powers have since blamed Russia for what they claim was a retaliatory strike on a UN convoy on September 20.»
