Before the start of business, Just Security provides a curated summary of up-to-the-minute developments at home and abroad. Here’s today’s news.

NORTH KOREA

North Korea launched a missile over the Japan this morning local time and landed in the Pacific Ocean, Pyongyang firing the intermediate-range ballistic missile in defiance of the U.N. Security Council’s vote on Monday imposing new sanctions against the regime. Alastair Gale and Kwanwoo Jun report at the Wall Street Journal.

The launch was the second in less than three weeks that passed over Japan, prompting angry responses from the international community, including Secretary of State Rex Tillerson who said in a statement that the U.N. sanctions were “the floor, not the ceiling” and that China and Russia should take “direct action” to put pressure on North Korea’s economy, including restricting oil supplies. Anna Fifield and Dan Lamothe report at the Washington Post.

Japan would “never tolerate” such “dangerous provocative action,” Japanese Prime Minister Shinzo Abe said in response to the launch, the U.N. Security Council is set to meet today in New York at the request of the U.S. and Japan. The BBC reports.

The latest launch would result in further diplomatic and economic isolation of Pyongyang, South Korean President Moon Jae-in said today, a spokesperson for Moon also adding that the President “ordered officials to closely analyze and prepare for new possible North Korean threats like E.M.P. (electro-magnetic pulse) and biochemical attacks.” Reuters reports.

The launch was the longest-ever test flight conducted by the regime and traveled about 3,700km (2,300m) and reached a maximum height of 770km (478m), Kim Tong-Hyung and Foster Klug report at the AP.

Neither the U.S. nor Japan attempted to intercept the missile, possibly because it was clear that the missile was not aimed at land and, in the U.S.’ case, the missile did not pose a threat to the U.S. mainland or its territory of Guam. Choe Sang-Hun and David E. Sanger report at the New York Times.

The size of North Korea’s Sept. 3 missile launch “equates to a hydrogen bomb,” the chief of U.S. Strategic Command Gen. John Hyten said yesterday, telling reporters that it could not be confirmed that it was a hydrogen bomb, but the test was nevertheless significant and it has to be assumed that Pyongyang has the ability to make a hydrogen bomb. The AP reports.

President Moon has to juggle a belligerent North Korea with the U.S. who has taken an aggressive approach to the crisis, as well as keeping his supporters on side – who expect Moon to pursue dialogue and diplomacy. James Griffiths explains Moon’s difficult balancing act at CNN.

North Korean leader Kim Jon-un is likely to be motivated by rational concerns and he understands regional politics. Fareed Zakaria imagines an interview with Kim at the Washington Post.

IRAN

The Trump administration yesterday waived a wide range of sanctions against Iran in accordance with the 2015 nuclear agreement, but imposed new Treasury sanctions against 11 firms and individuals working with Iran’s Islamic Revolutionary Guard Corps (I.R.G.C.) in an attempt to rein in Tehran’s ballistic missiles program, cyberattacks and support for terrorism. Felicia Schwartz, Laurence Norman and Ian Talley report at the Wall Street Journal.

“Certainly at a minimum the spirit of the deal is atrociously kept,” Trump told reporters on Air Force One yesterday and, when asked about the decision whether to certify Iran’s compliance with the deal, Trump said “you’ll see what I’m going to be doing very shortly in October,” making the comments as new sanctions were levied against individuals and firms connected to the I.R.G.C., the BBC reports.

“We have to consider the totality of Iran’s activities and not let our views be defined solely by the nuclear agreement,” Secretary of State Rex Tillerson said yesterday during a visit to Britain to meet Prime Minister Theresa May and Foreign Secretary Boris Johnson and before the U.S. announced that it had imposed sanctions against Iranian individuals and firms, Tillerson stating that Iran’s support for Syrian President Bashar al-Assad, its ballistic missiles program and cyber activities are “clearly in default” of the expectations in the preface of the Joint Comprehensive Plan of Action (J.C.P.O.A.). William James reports at Reuters.

The decision to waive the sanctions was significant as reimposing sanctions would have violated the J.C.P.O.A., allowing Iran to walk away from the deal and allow it to develop its nuclear weapons arsenal, signaling a potential shift in the Trump administration’s policy that may see the president maintaining the nuclear accord. David E. Sanger explains at the New York Times.

The waiver was a “holding action” pending a “final decision” by the president and his cabinet over its approach to Iran, an anonymous senior administration official said yesterday, Al Jazeera reports.

A leaked memo circulated on Capitol Hill has advocated that Trump declare his readiness to impose a “de-facto global economic embargo” on Iran if it failed to meet certain conditions over a 90-day period. Jana White and Dan De Luce reveal the memo written by former Republican congressional aide Richard Goldberg at Foreign Policy.

RUSSIA-BELARUS MILITARY EXERCISES

David Filipov reports at the Washington Post.

IRAQ

The Islamic State group claimed responsibility for an attack in southern Iraq yesterday that killed 84 people and wounded almost 100, according to the head of the provincial health directorate. Ghassan Adnan, Ali A. Nabhan and Isabel Coles report at the Wall Street Journal.

The attack targeted a route used by Shi’ite pilgrims visiting holy shrines in Karbala and Najaf, Tamer El-Ghboashy and Mustafa Salim report at the Washington Post.

The Iraqi Kurdistan independence has no international support at this moment, the U.S. special envoy to the coalition against the Islamic State Brett McGurk said yesterday, stating that he was encouraged that the Kurdish region could delay the vote. Reuters reports.

The U.S. and Iran are united in their desire to defer the Iraqi Kurdistan independence referendum, however this does not mean that the adversaries have shared motivations and a vote for independence could bring the U.S. and Iran closer to conflict. The Economist explains.

CUBA EMBASSY “INCIDENTS”

U.S. officials are investigating the cause of symptoms suffered by 21 people linked to the U.S. Embassy in Cuba, State Department spokesperson Heather Nauert said yesterday, noting that the department is “very deeply concerned” about the incidents which have some in the media have reported as an “acoustic attack” or a “sonic weapon.” Reuters reports.

The symptoms include hearing loss and mild brain damage, causing confusion among U.S. officials who have tried to determine the cause and motive of the mysterious attacks. The AP explains.
