If a dual France-US citizen gets drafted by both France and the US in the event of a war, must the individual join the French or the US army?

If both, can they avoid getting fined/jailed/punished for not joining one of the two armies?

Assume the individual is a male if that matters.

https://www.vie-publique.fr/fiches/23908-quen-est-il-du-devoir-de-defense (government website) indicates that France has a military draft in case of war:

Depuis la levée en masse des Français de 1792, afin de défendre "la Patrie en danger" et de renforcer l’armée française, le devoir de défense du territoire est lié à la citoyenneté. Tout Français de sexe masculin est donc susceptible d’être mobilisé afin de défendre le territoire national, ou, plus largement, de se battre pour son pays (y compris sur un théâtre d’opération extérieur à la France).


Since the mass levy of the French in 1792, in order to defend "the Fatherland in danger" and to strengthen the French army, the duty to defend the territory has been linked to citizenship. Any French man is therefore likely to be mobilized in order to defend the national territory, or, more generally, to fight for his country (including in a theater of operation outside France).


Si guerre, obligé d'aller combattre ? Oui tu seras réquisitionné car tes devoirs de citoyens t'obligent à défendre ton pays et ses valeurs.


If war, forced to go to fight? Yes, you will be requisitioned because your duties as citizens oblige you to defend your country and its values.

  • @DavidSupportsMonica I've added a quote that claims France has a military draft in case of war. – Franck Dernoncourt Jun 6 '20 at 19:18
  • @DavidSupportsMonica vie-publique.fr/fiches/23908-quen-est-il-du-devoir-de-defense (government website) confirms that France has a military draft in case of war. – Franck Dernoncourt Jun 6 '20 at 19:22
  • That's a much more persuasive source, thanks. So France does indeed have a statutory draft, although it it not now being exercised or enforced. That satisfies my objection d), but still leaves a), b), and c) in place. I still think the original question will generate only opinion-based and speculative answers. – DavidSupportsMonica Jun 6 '20 at 19:25

    @DavidSupportsMonica ok but if this gets closed and I later get into trouble during ww3, you give me a discount on your attorney fees ;) – Franck Dernoncourt Jun 6 '20 at 19:40

    I tried real hard to add "<g>" as a response, but the system won't let me. – DavidSupportsMonica Jun 6 '20 at 19:42
