North Korean leader Kim Jong Un threatened “more offensive actions” to repel what he called increasing United States-led military threats after he supervised the third test of his country’s most advanced missile designed to strike the mainland U.S., state media reported Tuesday.

Kim’s statement suggests he is confident in his growing missile arsenal and will likely continue weapons testing activities ahead of the 2024 U.S. presidential election. But many observers say North Korea still needs to perform more significant tests to prove it has functioning missiles targeting the U.S. mainland.

After watching Monday’s launch of the Hwasong-18 intercontinental ballistic missile, Kim said the test showed how North Korea could respond if the United States were to make “a wrong decision against it,” according to the official Korean Central News Agency.

Kim stressed the need to “never overlook all the reckless and irresponsible military threats of the enemies … and to strongly counter them with more offensive actions,” KCNA said.
