WASHINGTON — Warning of “fire and fury,” President Donald Trump has answered North Korea’s threats with rhetoric the nuclear-armed nation might appreciate. The risk is the tough talk leading to war.

Trump’s foray into North Korea-style bombast injects new uncertainty into the increasingly fragile, 6-decade-old truce between the United States and the communist country. His talk of military action “like the world has never seen” jars with the message of top American officials to cooperate with China on pressuring North Korea and ultimately seek diplomatic negotiations.

The type of threats Trump issued are routine from the isolated, Stalinist state, which often speaks of turning neighbor South Korea’s capital into a “sea of fire” and warns of “merciless” and unprecedented attacks on its enemies, including nuclear strikes on the United States. The bombast is so frequent that it is difficult to judge the seriousness, particularly as the North has not used its massive conventional arms stockpiles against its neighbors or U.S. military bases in South Korea and Japan.

Trump, too, has earned a reputation for exaggeration and sometimes unsubstantiated policy directives, often delivered via Twitter. Markets showed no reaction to Trump’s threat, and there was no indication the Pentagon was adjusting its military posture.

On Tuesday, Trump told reporters: “North Korea best not make any more threats to the United States.”

Then, on Wednesday, he issued a series of tweets extolling the U.S. nuclear arsenal. “Hopefully we will never have to use this power, but there will never be a time that we are not the most powerful nation in the world!” he said.

Trump’s critics were quick to pounce, suggesting he risked playing into North Korean efforts to divide the U.S. from its military-averse allies in Asia and reinforcing claims that Washington isn’t interested in nuclear disarmament, and really wants to oust the Kim family dynasty.

“You got to be sure you can do what you say you’re going to do,” Republican Sen. John McCain, a frequent Trump critic, said of the president’s comments. “That kind of rhetoric, I’m not sure it helps. The great leaders I’ve seen don’t threaten unless they’re ready to act and I’m not sure that President Trump is ready to act.”

North Korea experts have long advised against overtly hostile threats to the North, particularly given how little is known about the country’s unpredictable young leader, Kim Jong Un, and his stewardship of the world’s largest standing army.

North Korea returned Trump’s threats with a “serious warning” of its own. An unnamed army spokesman was quoted in state media talking about “enveloping” America’s Pacific territory of Guam in missile fire to counteract U.S. bombers that are based there and fly over South Korea — and “get on the nerves” of the North.

Although it wasn’t clear if Trump and the Koreans were responding directly to each other, the heightened rhetoric added to the potential for a miscalculation that might bring the nuclear-armed nations into conflict.

Flying to Guam for a refueling stop on his way back from Asia, Secretary of State Rex Tillerson told reporters that Trump “is sending a strong message to North Korea in language that Kim Jong Un can understand, because he doesn’t seem to understand diplomatic language.”

Trump, he said, wanted to make it clear to the North Korean leadership about “the U.S. unquestionable ability to defend itself” and that the president’s message was designed to “avoid any miscalculation on their part.”

Tlllerson said Americans should sleep soundly: “Nothing that I have seen and nothing that I know of would indicate that the situation has dramatically changed in the last 24 hours.”

Meantime, The Washington Post reported that U.S. intelligence officials believe the North can now fit a nuclear bomb on a missile. Its recent tests of intercontinental missiles appear, after years of North Korean efforts, to have finally put the U.S. in range.

It wasn’t clear what threats Trump was referring to when he addressed reporters Tuesday. On Monday, the North criticized a new set of U.N. sanctions and said it would make the U.S. pay a “thousand-fold for all the heinous crimes” committed against the North.

Democrats accused Trump of making a dangerous situation worse.

“North Korea is a real threat, but the President’s unhinged reaction suggests he might consider using American nuclear weapons,” said Rep. Eliot Engel, the top Democrat on the House Foreign Affairs Committee.

Sen. Dianne Feinstein, the Senate Intelligence Committee’s leading Democrat, lamented Trump’s “bombastic” comments at a time high-level dialogue with North Korea is needed.

If the North calls Trump’s bluff and conducts more missile launches or nuclear tests, Trump will be under added pressure now to deliver a forceful American response. If the North follows through on its Guam threat, Trump would have no choice.

All the threats raise the potential for an accidental conflict.

Even after North Korea’s bellicose response to the latest round of Security Council sanctions, Tillerson said Washington wasn’t seeking confrontation. He voiced his hope North Korea would “choose a different pathway,” one leading to a dialogue.

Such careful language had been a hallmark of official U.S. commentary on North Korea for decades, if only to prevent a minor incident touching off a major conflagration.

Until now.
