Why weren't the French Resistance executed?

[Cornfed]

The officially recognised French government reached an agreement with the Germans during WWll. It follows that both under French law and International law, French citizens were required to abide by this armistice, which was a legal command of the French government. But, you say, this agreement was coerced. Well of course all armistices are coerced to some extent. What, should every war result in one side fighting to the death? Of course not, so it follows that they were all traitors who should have faced execution. Not that what they did ever really amounted to anything anyway, but perhaps the victims of their crimes could sue for restitution.
