A U.S. Ambassador in Europe, who has extensive experience dealing with Russia, told me that he and other State Department officials who would need to know have received no post-summit briefings, or even talking points about what happened, both of which would be standard practice after such an important encounter. “Nothing,” he told me. “We are completely in the dark.

We are witnessing nothing less than the breakdown of American foreign policy. This week’s extraordinary confusion over even the basic details of the Helsinki summit shows that all too clearly. We may not yet know what exactly Trump agreed to with Putin, or even if they agreed to anything at all; perhaps, it will turn out, Putin and his advisers have sprung another clever disinformation trap on Trump, misleading the world about their private meeting because a novice American President gave them an opening to do so. But, even if we don’t know the full extent of what was said and done behind closed doors in Helsinki, here’s what we already do know as a result of the summit: America’s government is divided from its President on Russia; its process for orderly decision-making, or even basic communication, has disintegrated; and its ability to lead an alliance in Europe whose main mission in recent years has been to counter and contain renewed Russian aggression has been seriously called into question.
