In the last few years we have witnessed a new surge in the investment in nuclear energy on the global level (IEA). Ever since the foundation of the initiative “International physicians for the prevention of nuclear war” in the 1980s, there have been relentless reminders of the devastating effects of such a war. In 2023 we are all aware of the real risk of attacks on the biggest nuclear power plant located in Ukraine. Nevertheless we continue to invest heavily in power plants that constitute a massive risk at times of war between irresponsible nations. Besides the publication of many high quality papers in The Lancet there is regularly space to keep the awareness of the dangers of nuclear war at a high level. Too many politicians shield themselves from dealing with such realistic dangers in the interest of supposed cheap and save energy for all. Both is no longer the case. Nuclear energy is expensive and unsafe in peace and horrible in war times. We cannot afford to abstract from these rising risks. The hype about anything nuclear like in the 1980s is grossly displaced (image of book below).
