Korea Displays F-35 Stealth Jets Seen by North as a Threat Reuters SEOUL - South Korea showcased newly acquired F-35 stealth fighter jets to mark Armed Forces Day on Tuesday as President Moon Jae-in tries to allay concerns that his policy of engagement with North Korea may be weakening the South's commitment to defense. North Korea has criticized the South's weapons procurement and its joint military drills with the U.S. military as undisguised preparations for war that were forcing it to develop new short-range missiles. Moon has thrown his support behind dialogue to end the North's nuclear and ballistic missile programs, urging that working-level negotiations between the North and the United States be held soon. No new dates or locations have been set. Moon marked the founding of the South Korean military at a ceremony at an airbase in the city of Taegu that highlighted four of the eight Lockheed Martin F-35A jets delivered this year. Forty of the aircraft are to be delivered by 2021. .
