What would happen if we dropped a nuclear bomb on a city

As you know, we love to blow things up on this channel. So when the International Red Cross contacted us and offered to collaborate on a video about nuclear weapons, we were extremely excited.
Until we started researching. Turns out we forgot a bit about the actual impact of nuclear weapons in real life, on a real city. And especially, even the most developed countries on earth will be helpless if a nuclear attack really occurs.
So we hope this video will help you understand this extremely unpleasant truth about a nuclear attack in a less gruesome way. This collaborative video was a fun experience and we would like to send our sincere thanks to the International Red Cross!
