North Korea's Provocative Missile Launches Amidst US Threats

North Korea has fired a suspected intercontinental ballistic missile (ICBM) that flew for over an hour before landing in the sea near Japan. The launch comes after North Korea threatened retaliation against alleged US spy plane incursions. The US and South Korea have increased joint military drills in response to North Korea's continued missile launches. South Korean and US officials have condemned the launch as a violation of UN Security Council resolutions. North Korean leader Kim Jong Un has vowed to increase the country's production of nuclear warheads and development of more powerful weapons.
