We share the same problems that Canada has. Those illnesses are very insidious and not always easy to diagnose. In fact, very few countries have a lot of experience in this area. Perhaps this is mainly due to the military itself, which is still reluctant to recognize this type of pathology because it is not always easy to explain in a military context.
In my view, France is in the same position as Canada. There is probably still a lot of room for improvement to help people suffering psychological damage when they come home.
