Speaking in front of South Korea’s National Assembly Wednesday morning, President Trump warned North Korea: “Do not underestimate us.”

“Today, I hope I speak not only for our countries but for all civilized nations when I say to the North: Do not underestimate us. And do not try us,” Trump said.

Trump, who is often at his best when traveling abroad, stood confident and proud during his speech. “We will defend our common security, our shared prosperity, and our sacred liberty,” Trump said.

Trump’s tone and matter-of-fact comments took a different direction than his remarks from days ago when he appeared open to possible talks with North Korean leader Kim Jong Un.

The speech in South Korea comes amid a 13-day trip to Asia that has already seen the president visit Japan and South Korea, with stops in China, Vietnam, and the Philippines still on the calendar. Trump is planning to meet with Vladimir Putin when the two are in Vietnam.
