The US has defended its decision to refrain from vetoing a UN Security Council (UNSC) resolution condemning Israeli settlement building in Palestine, saying the unusual step was taken only after all negotiating options to pursue a two-state solution were exhausted.
President-elect Donald Trump meanwhile slammed the outgoing Obama administration for abstaining from voting.
"As to the UN, things will be different after Jan 20th," he tweeted.
In a move seen as a diplomatic rebuke to its closest Middle East ally, the United States had decided not to veto the resolution demanding an end to Israeli settlements on Palestinian territory, introduced in the UNSC by Egypt.
"The United States acted with one primary objective in mind: to preserve the possibility of the two-state solution, which every US administration for decades has agreed is the only way to achieve a just and lasting peace between Israelis and Palestinians," said secretary of state, John Kerry.
"One of our grave concerns is that the continued pace of settlement activity -- which has accelerated significantly since 2011, when we vetoed the UNSC resolution that condemns settlements -- puts at risk the two-state solution, as does any continued incitement to violence," Ben Rhodes, deputy national security advisor told reporters during a conference call on Friday afternoon.
"In that context, we therefore thought that we could not in good conscience veto a resolution that expressed concerns about the very trends that are eroding the foundation for a two-state solution," Rhodes said in defence of the decision.
Describing this as a rebuke to Israel, The Washington Post said decision not to veto reflected frustration from the Obama administration over the settlements and defied pressure from Trump.
A day earlier, Trump, in a tweet, had asked the US to veto the resolution. Rhodes stressed that the US had exhausted every effort to pursue a two-state solution through negotiations, discussions and confidence-building measures.
"We gave every effort that we could to supporting the parties coming to the table. So within the absence of any meaningful peace process, as well as in the face of accelerated settlement activity that put at risk the viability of a two-state solution, that we took the decision that we did today to abstain on this resolution," he said.
The deputy national security advisor said the US does have concerns about the UN as a venue for addressing aspects of the Israeli-Palestinian conflict. "That is why, for instance, we have consistently resisted efforts to impose a solution to the conflict through the United Nations, through the drawing of borders, or the recognition of a Palestinian state," he said.
