The US found itself without much support at the Security Council where even one of its closest allies, the UK, said Britain disagrees with Trump's move on Jerusalem.
The United States stood alone Friday as one after another fellow UN Security Council member criticised its decision to recognise Jerusalem as Israel's capital.
The debate unfolded at a largely symbolic emergency meeting of the council – no vote on a resolution was planned, as the US has veto power – two days after President Donald Trump reversed two decades of US policy on the holy city.
The meeting was convened by no fewer than eight of the 14 non-US members of the council.
This vivid show of discord was triggered by Trump's announcement, which included plans to move the US embassy in Israel from Tel Aviv to Jerusalem.
Asked what he expected to come from the UN meeting, one diplomat said: "Nothing." Another said the session would show US "isolation" on the issue.

Spiral of violence
The UN coordinator for the Middle East peace process, Nikolay Mladenov, warned that the US decision could lead to a spiral of violence among Palestinians and others angered by what Trump has done.
Indeed, clashes between Palestinians and Israeli security forces Friday left one person dead after calls for a "day of rage" from Hamas.
British ambassador to the UN Matthew Rycroft said flat out that Britain disagrees with Trump's move on Jerusalem and the embassy location.
"These decisions are unhelpful for the prospects for peace in the region," Rycroft said.
He urged Trump to now come up with detailed proposals for an Israel-Palestinian peace accord, a goal which has eluded the US and the international community for decades.
The status of Jerusalem is one of the most hotly-contested issues in the Israeli-Palestinian conflict.
Israel seized control of the east of the city in 1967 and later annexed it in moves never recognized by the international community.
Israel considers the city its undivided capital, but Palestinians believe the east is illegally occupied and see it as the capital of their future state.
Not in line
Five European countries on the council insisted the new US policy is not in line with UN resolutions, including one that considers east Jerusalem to be Israeli-occupied.
At Friday's meeting, US Ambassador to the UN Nikki Haley defended Trump as remaining committed to the peace process and a two-state solution if the Israelis and Palestinians choose this.
Haley said that in his reversal of US foreign policy, Trump was simply recognising reality, since the Israeli government and parliament are located in Jerusalem.
And she recalled that Trump insists his decision has no impact on whatever Israelis and Palestinians ultimately decide on boundaries and borders of the city, which is holy to Muslims, Christians and Jews.
"I understand the concerns that members have in calling this session," Haley said. "Change is hard."
