I want to go to France to join a foreign legion, which is my biggest dream in my life. But I can't speak French. Can't I speak French?

French doesn't matter, but you should be able to communicate skillfully in English, but personally, joining the French foreign legion is not a good idea. In fact, the status of foreign legion in France is not high, and the conditions are not job advertisements or what everyone tells you. Even in many wars before, the casualty rate of foreign legions was very high, and many things were obviously unspeakable, hehe.
