When starting out this fact check I looked at who was posting the content and found that the person is a part of a podcast and post mainly about their personal opinions on political views. The post is an opinion that has no claims to back up the statement. There is also a bit of irony in the statement when they are rooting for Germany to have the "bomb." I did find some articles that talk about how France is thinking about extending their nuclear umbrella.
