The G20 became the G19 as it ended. On the Paris climate accords the United States was left isolated and friendless.
It is, apparently, where this US President wants to be as he seeks to turn his nation inward.
Donald Trump has a particular, and limited, skill-set. He has correctly identified an illness at the heart of the Western democracy. But he has no cure for it and seems to just want to exploit it.
He is a character drawn from America’s wild west, a travelling medicine showman selling moonshine remedies that will kill the patient.
And this week he underlined he has neither the desire nor the capacity to lead the world.
Given the US was always going to be one out on climate change, a deft American President would have found an issue around which he could rally most of the leaders.
He had the perfect vehicle — North Korea’s missile tests.
So, where was the G20 statement condemning North Korea? That would have put pressure on China and Russia? Other leaders expected it and they were prepared to back it but it never came.
There is a tendency among some hopeful souls to confuse the speeches written for Mr Trump with the thoughts of the man himself.
