Mr. Trump did order a review of USA nuclear posture and strategy early in his presidency, but that's different from modernization and bringing old systems up to usable standards. "It is now far stronger and more powerful than ever before", he wrote on Twitter.
After President Trump was inaugurated, it was noticed in various reports that due to decades of war and corruption, the United States military strength remains severely depleted. "The nuclear arsenal is somewhat smaller than it was 201 days ago because we are in the process of reducing nuclear weapons in compliance with the New START Treaty".
Later in the day, on Fox News, Gorka said that he had been "admonishing the journalist" who, he said, had asked the top U.S. diplomat to make "the military case for action, when that is not the mandate of the Secretary of State". "You don't just initiate a modernization plan", she said. Trump signed an executive order after he took office in January to initiate a review of the country's nuclear policy and strategy.
When host Tim Russert pushed back against the idea of military action against North Korea, Trump insisted that it was better to consider striking early rather than wait for North Korea to get stronger. If they think you're serious, they'll negotiate and it'll never come to that.
"What they've been doing and what they've been getting away with is a tragedy and it can't be allowed", Trump said.
"I think that the president, again, as commander-in-chief, I think he felt it necessary to issue a very strong statement directly to North Korea", he added.
China, which is North Korea's closest ally despite its anger at Pyongyang's missile and nuclear programs, described the situation as "complex and sensitive", and urged calm and a return to talks.
"The words were his own", said Sarah Huckabee Sanders. Tens of thousands of USA troops remain stationed in South Korea and in nearby Japan.
