In his speech, he also addressed in length Iran, slamming the nuclear deal with Tehran and echoing statements he made during last year's UN General Assembly speech that rather than blocking Iran's path to the bomb, "it paves it".
The Trump administration has twice certified that Iran is complying with the agreement but has said he would not keep doing so indefinitely.
"By violating its global commitments, the new U.S. administration only destroys its own credibility and undermines worldwide confidence in negotiating with it or accepting its word or promise". Chinese Foreign Minister Wang Yi also reiterated support.
In remarks clearly directed at Trump's 8-month-old administration, Iranian leader Hassan Rouhani told the U.N. General Assembly: "It will be a great pity if this agreement were to be destroyed by rogue newcomers to the world of politics". That's not so clear, according to French President Emmanuel Macron, who met with President Trump earlier this week.
It will be a tall order for the Trump administration to reconcile the president's isolationist inclinations and America First proclamations with the leadership role the United States has played in global affairs since World War II.
The IAEA has the authority to request access to facilities in Iran, including military ones, if there are new and credible indications of banned nuclear activities there, but diplomats say Washington has yet to provide such indications.
Royce, in his CNN interview, said the right course was to focus on making sure Iran continued to hold up its end of the agreement, as well as pushing back on Iran throughout the region, particularly by keeping its forces away from Israel.
The UN atomic watchdog has confirmed Tehran's compliance to the deal but the U.S. administration says the "technical" adherence is not enough as long as Iran tests ballistic missiles and exerts influence in the region.
"When the announcement is made, it will fit into a fundamentally sound and broad strategy aimed at addressing Iran's destabilizing behavior and prioritizing protecting American vital interests", McMaster said on NBC's Today show.
"Our approach to Iran has to change fundamentally", McMaster said on CBS.
PAAIA strongly urges the Administration to continue implementing the JCPOA, a deal which could help avoid another disastrous war in the Middle East. The European Union's foreign policy chief, Federica Mogherini, chairs the joint commission that is monitoring the deal's implementation.
"Whether we can agree, that's another thing", Tillerson said.
Wang said all parties should look at the positive side of the JCPOA as no agreement is flawless.
Trump is obliged to certify to Congress by October 15 if Iran is complying with the deal, and officials have said he may use that occasion to either declare Iran in violation or determine that the agreement is no longer in the US national security interest.
Both Trump and Netanyahu have been scathingly critical of the accord, with the United States leader due to make a decision on re-certifying it next month.
"We should be hoping cooler heads prevail", said Andersen-Rodgers, adding later, "There's no reason to be in this position".
