The World Once Laughed at North Korean Cyberpower. No More.

And just as Western analysts once scoffed at the potential of the North’s nuclear program, so did experts dismiss its cyberpotential — only to now acknowledge that hacking is an almost perfect weapon for a Pyongyang that is isolated and has little to lose.The country’s primitive infrastructure is far less vulnerable to cyberretaliation, and North Korean hackers operate outside the country, anyway. Sanctions offer no useful response, since a raft of sanctions are already imposed. And Mr. Kim’s advisers are betting that no one will respond to a cyberattack with a military attack, for fear of a catastrophic escalation between North and South Korea.PhotoPortraits of the former North Korean leaders, Kim Il-sung and Kim Jong-il, on a building in Pyongyang.Credit Ed Jones/Agence France-Presse — Getty Images“Cyber is a tailor-made instrument of power for them,” said Chris Inglis, a former deputy director of the National Security Agency, who now directs cyberstudies at the United States Naval Academy.

Prospect of Atmospheric Nuclear Test by North Korea Raises Specter of Danger

“It is not clear North Korea has that capability yet,’’ said Siegfried S. Hecker, the former director of Los Alamos National Laboratory and the nuclear weapons expert the North Koreans let in to see their uranium enrichment plants years ago, when they wanted to make clear to the Obama administration that their atomic weapons program was moving ahead, unimpeded by sanctions.“Besides,” said Dr. Hecker, now a professor at Stanford University, “a live missile test — one loaded with an H-bomb — poses enormous risk.” He recalled that when the United States performed such tests in the early days of the Cold War, “one blew up on the launchpad and one had to be destroyed right after launch, creating significant radioactive contamination.”The North Koreans have studied this history, too, according to current and former American intelligence officials. But the appeal of an atmospheric test is obvious: It would create a sense of fear that an explosion deep inside a tunnel in North Korea does not. The underground tests are detected on a Richter scale; an atmospheric test, like the kind the United States conducted at Bikini Atoll starting in 1948, creates a terrifying mushroom cloud.Continue reading the main storyThe largest of those, a 1954 test code-named Castle Bravo, turned out to be roughly three times larger than American bomb designers anticipated […]

White House Weighs Response to North Korea’s Threats

“When does rhetorical bombast turn into a real bomb?” Senator Benjamin Cardin of Maryland, the top Democrat on the Senate Foreign Relations Committee, said in an essay for Foreign Policy magazine. “The president’s inflammatory and irresponsible threat does not keep America or our Asian allies safe.’’Other presidents have responded viscerally to North Korean leaders but not so publicly.

Trump Vows to ‘Totally Destroy’ North Korea if It Threatens U.S.

“No nation on Earth has an interest in seeing this band of criminals arm itself with nuclear weapons and missiles,” Mr. Trump said. “The United States has great strength and patience, but if it is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea. Rocket Man is on a suicide mission for himself and for his regime.”Without mentioning it by name, Mr. Trump also chastised China for continuing to deal with its rogue neighbor. “It is an outrage that some nations would not only trade with such a regime, but would arm, supply and financially support a country that imperils the world with nuclear conflict,” the president said.He went on to assail the Iran agreement, which was negotiated by President Barack Obama and leaders of five other powers and ratified by the United Nations Security Council to curb Tehran’s nuclear program for a decade in exchange for lifting international sanctions.

A Potent Fuel Flows to North Korea. It May Be Too Late to Halt It.

Some experts are skeptical that the North has succeeded in domestic production, given the great difficulty of making and using the highly poisonous fuel, which in far more technically advanced nations has led to giant explosions of missiles and factories.In public, at least, the Trump administration has been far more focused on ordinary fuels — the oil and gas used to heat homes and power vehicles. The United States has pushed to cut off those supplies to the North, but it settled last week for modest cutbacks under a United Nations resolution.Nonetheless, on Sunday the president made a case that those sanctions were having an effect. He wrote on Twitter that he had spoken with South Korea’s president, Moon Jae-in, and tossed out a new nickname for the North’s leader, Kim Jong-un.“Asked him how Rocket Man is doing,” President Trump wrote. “Long gas lines forming in North Korea. Too bad!”But inside the intelligence agencies and among a few on Capitol Hill who have studied the matter, UDMH is a source of fascination and seen as a natural target for the American effort to halt Mr. Kim’s missile program.“If North Korea does not have UDMH, it cannot threaten the United States, it’s as simple as that,” said Senator Edward J. Markey, Democrat of Massachusetts, who sits on the Senate Foreign Relations Committee. “These are the issues that the U.S […]
