The level of tension on the Korean peninsula remains high due to a series of nuclear and missile tests by the DPRK (North Korea), including two intercontinental ballistic missile tests in July 2017 and 1 in November 2017, two nuclear tests in 2016 and a nuclear test on 3 September 2017. There remains a threat of further missile or nuclear tests, which could lead to further instability in the region. The level of tension and the security situation can change with little notice. Tensions usually rise around the time of the regular South Korean-US military exercises, notably those held in March and August. In the past, heightened tensions haven’t affected daily life.
