Team Trump not really excelling at the diplomacy game.
The one sided acknowledgement of Jerusalem as Israel's capital is not only flying in the face of the two state peace plan as proposed by the UN and the Big Four, it has also pissed of the entire Muslim World, including key US allies such as Saudi Arabia, Egypt, Turkey and Jordania.
So, first the UN security council voted 14-1 to condemn the move, the one dissenting vote of course belonging to the USA, and because they have the right to veto any decision, the count does not count. But it is still quite a snub.
Then the general assembly voted, and the US then made sure to piss off every one even more, by threatening to retaliate against any nation daring to vote against the US. This stroke of genius ensured an impressive backup of the US position by no less than eight nations: Israel (duh), Guatemala, Honduras, the Marshall Islands*, Micronesia, Nauru, Palau and Togo. So, sure, the combined population of the Marshall Islands, Micronesia, Nauru and Palau only amounts to 200,000 people, so slightly more than Abbotsford, but still. On paper they count as four nations, or half the pro-US stance group.
35 countries (including Canada and Mexico, who maybe because of their awkward geographical position actually were shaken by the retaliatory threats) abstained, while 128 nations, including 24 out of 29 EU members, voted to condemn the US action.
It seems clear by now the US has abandoned it's role as the leader of the free world.
No one is listening to them any longer.

Had to doublecheck that this is even a nation. Back when I was in school it was still US territory, but yeah, seems the 56,000 people residing there attained independence in 1986. Who knew. And despite the US having used their attolls and islands as a test site for nuclear bombs, they seem a staunch supporter.
