Yes, I hadn't read the all thing. Oops, sorry.
However, in T2K I don't understand why France withdraws from NATO (not at the given point). It has no reason to do so (that is also true for Italy) as no NATO member is entitled to get into the twilight war. As I pointed out, Germany is the agressor and, therefore, no treaty member is bound by the treaty. That's an entirely different matter for the Warsaw Pact when it comes to the European theater (Romania is effectively a traitor).
Nevertheles, the french position in T2K is plausible and fits the game well (IMO). Actually, I'm not using it in my game : instead, france betrays its alliance when the first nukes start to fall and sign a separate peace with Moscow (probably a revenge from someone who was born belgian
).
Anyway, in all cases I see even less ground for France to get back in NATO at any given point. France finally declares war to NATO (and in its case, every NATO member has to declare war to France). Hey, the french attacked Germany, Netherland and Canada (That is when France should withdraw from NATO, when it becomes an aggressor). Moreover, it probably represents a threat to NATO shipping almost on every see. That can also make the french involvement in the Middle East doubtfull but, after all, the situation is a mess and, by 2000, NATO must have become meaningless.
