Iserlohn sets an example for peace: flag raised for nuclear disarmament!

On Tuesday, July 8, 2025, numerous cities in Germany will raise the “Mayors for Peace” flag, sending an impressive signal for nuclear disarmament. Over 600 cities, including Iserlohn, took part in this campaign, which commemorates the 80th anniversary of the atomic bombings of Hiroshima and Nagasaki. Mayor Michael Joithe addressed the assembled citizens with clear words: Nuclear weapons are not a security gain, but a serious risk for humanity. This statement underpins the fundamental message of the “Mayors for Peace,” which has been campaigning for a world without nuclear weapons since its founding in 1982 by the mayor of Hiroshima.

Flag Day is not only a symbol, but also commemorates a legal opinion from the International Court of Justice from 1996, which found that nuclear weapons violate international law. This is particularly relevant as the Mayors for Peace network now includes more than 8,480 cities in 166 countries working for peace and against the risks of nuclear war. Recent developments in the geopolitical landscape also raise concerns. According to the Stockholm International Peace Research Institute (SIPRI), there are currently about 12,241 nuclear warheads worldwide and all nine nuclear powers are working to modernize their arsenals.

Global responsibility and the danger of a new arms race

Amid all these challenges, members of the Mayors for Peace warn that it is high time to stand up for peace and disarmament. Mayor Marc Buchholz emphasized the responsibility of cities to spread knowledge about the destructive power of nuclear weapons and to actively work to ban them. This is not just a reminder of the devastating consequences of the use of nuclear weapons; The survivors, the Hibakusha, also warn urgently about the further consequences of such attacks.

One worrying aspect is the current modern defense projects, especially in countries like China, which are heavily focused on defense modernization. The New START Treaty between the US and Russia, a key element in limiting nuclear arsenals, expires in early 2024 and there is no sign of an extension or a new treaty. This uncertainty could lead to another nuclear arms race.

A call for collaboration

The “Mayors for Peace” not only advocate the abolition of nuclear weapons, but also strive for peaceful solutions to conflicts. This initiative can be seen particularly well in the example of cities in Germany, where there are over 800 members in the network. As a “Lead and Executive City”, Hanover is a driving force in these efforts and faces the challenge of advancing dialogue on the topic of disarmament and peace.

Given the current geopolitical tensions, particularly the risks posed by the Russian invasion of Ukraine, the danger of nuclear war is becoming apparent. An end to the nuclear arms race, which is being further fueled by the deployment of new cruise missiles in Europe, is crucial for future security. Those responsible are appealing to the community to work together to shape a world without a nuclear threat and to pool the voices of the cities.
