While North Korea broke with pledges of peaceful reunification in January, demolished the Unification Arch, and the country's leader Kim Jong Un announced the dissolution of institutions working to reunite the 2 countries, South Korea has not renounced this aspiration. At the Dora Observatory in the Demilitarized Zone, which offers a view of the border with North Korea, a movie about the war between the 2 countries ends with slogans about the necessity of reunification; despite the differences between the successive ruling teams of the Republic of Korea, the Ministry of Unification continues to operate uninterruptedly. According to Article 4 of the constitution, "The Republic of Korea shall strive for reunification, formulate and prosecute a policy of peaceful reunification based on the principles of freedom and democracy."
