United nations? This year, not so much, as global differences abound at UN General Assembly

This year’s UN gathering of world leaders put an immediate spotlight Tuesday on deep differences on tackling crises from North Korea to global warming: France’s president urged world leaders to work together, while America’s emphasised nations’ own sovereignty.

And UN Secretary-General Antonio Guterres warned that the threat of a nuclear attack is at its highest level since the end of the cold war and cautioned about the dangers of fiery rhetoric.

Macron, a centrist who embraced internationalism during his campaign, vowed to press ahead with the Paris accord to combat global warming, although the US has said it’s withdrawing from the agreement. In his speech and a subsequent news conference, Macron said he respects Trump’s decision but thinks it’s a mistake and will continue trying to persuade the American to reconsider.

Macron also said France won’t “close any door to dialogue” with North Korea and said it would be “a grave error” to unwind the 2015 nuclear deal with Iran, which faces strong criticism from Trump. Macron also called for investing in education and health and proposed appointing a UN representative for press freedom.

Seven decades after the end of World War II and the creation of the United Nations, international bodies are confronting doubts that they are merely venues for “a game for diplomats sitting around a table” and come up short on addressing such major threats as climate change.

But “today, more than ever before, we need multilateralism” to work on global warming, war, terrorism and other issues, Macron said.

Trump, a couple of hours earlier, portrayed “a coalition of strong and independent nations that embrace their sovereignty to promote security, prosperity, and peace,” but keep their own citizens’ interests foremost.

“I will always put America first,” and his counterparts “should always put your countries first,” Trump said. “America first” was one of his slogans from a campaign in which he often belittled the UN; he now says it has “tremendous potential.”

He told leaders that the United States seeks harmony and friendship, not strife, but he warned that America “can no longer be taken advantage of.”

North Korea’s mission said its ambassador and a senior diplomat left the chamber to boycott Trump’s speech, but left a note-taker to listen.

Iran’s semi-official ISNA news agency said Foreign Minister Mohammad Javad Zarif called Trump’s remarks “impudent and ignorant.”

Israeli Prime Minister Benjamin Netanyahu heaped praise on Trump’s comments and told the General Assembly that the Iran deal should be scuttled or changed to put more pressure on Tehran.

Israel sees Iran as its most dangerous adversary because of its nuclear programme, development of long-range missiles and support for militant groups in the region. Netanyahu warned that Israel would fiercely defend itself, but he made a point of telling everyday Iranians that Israel doesn’t see them as enemies – he even broke into Farsi, one of Iran’s main languages, to say: “You are our friends.”

Guterres, meanwhile, put “nuclear peril” as the leading global threat and added that “fiery talk can lead to fatal misunderstandings.”

His message was implicitly directed at North Korean leader Kim Jong-un, but also at the US and Trump. The two have traded tough rhetoric amid Pyongyang’s continuing nuclear and missile tests.

Guterres said a solution to North Korea’s activities must be political. “This is a time for statesmanship,” he stressed.

Beyond the nuclear threat, Guterres painted a grim picture of a troubled world facing grave challenges as people see rising insecurity, inequality, conflict and climate change in a world of polarised politics and fragmented societies.

“We are a world in pieces. We need to be a world at peace,” he said, later tweeting that “only together, as truly United Nations, can we build a peaceful world.”

By long tradition, Brazil’s leader is first to address the 193-member General Assembly – a custom carried on this year by President Michel Temer, who was charged last week with obstruction of justice and leading a criminal organisation. Temer denies wrongdoing.

He said that at “this time in history, marked by so much uncertainty and instability, we need more diplomacy, not less – and ”we need the UN more than before.“

But Temer said it needs reform, particularly expanding the powerful Security Council to align it with the reality of the 21st century. Brazil is part of a group with Germany, India and Japan seeking permanent seats on the council.
