President Donald Trump arrived in South Korea Tuesday for his two-day visit bearing a surprisingly diplomatic message: During a press conference with his South Korean President Moon Jae-in, Trump surprised his audience by delivering a message to North Korea that was unexpectedly conciliatory.

When asked about the monthslong diplomatic standoff between the two nuclear powers, Trump said he thinks the two countries are "making progress" toward a diplomatic solution, while urging the North Korean leadership to "come to the table and make a deal."

"I think we're making progress … I do see certain movement, yes, but let's see what happens," Trump said in Seoul, where he is spending two days of his 12-day tour of Asia.

Still, Trump noted that the North remains a threat to global order, and that the US stands ready to attack "if need be."
