Ok, I mainly said that because I was too lazy to bother typing an argument and i expected you to know the explanation because its common sense.
Germany will maybe build nuclear weapons in the future, except something stronger and more devastating comes out. But they wont use it to start a war. Hitler was stupid and wanted to conquer the world, but merkel isnt. All she does is her work. Shes maybe not good at it but idgaf since i dont care about politics.
Also building nuclear weapons is pricy and instead of wasting that for something youll never use, theyll use it for the refugees or whatever.
Here brought you an argument. I didnt even have to think about this much. Its all common sense, which you dont have apparently.
