Let me preface this by saying I'm a big fan of France. In fact, I think France was a good ally recommending caution with Iraq (precisely because they had the most recent experience with fighting a counter-insurgency in an Arab country).
But I take exception with your claim that France didn't end up with Gitmo.
Read 'A Savage War of Peace: Algeria 1954-1962'. France pretty much invented torturing arab terrorists.
Look at the UK & Northern Ireland.

Edit: This is about RAF in Germany http://en.wikipedia.org/wiki/Red_Army_Faction#Trial_manipula... (But certainly, maybe the lawyers were guilty, etc.)
Edit: This is about ETA in Spain (not so strong, but still) http://en.wikipedia.org/wiki/ETA#Human_rights http://en.wikipedia.org/wiki/Human_rights_in_Spain#Basque_se...
Can you precise?
I can talk about something I know. I'm french. France got problem with islamic terrorism in the 90's. France is having problem with terrorism for the last 10 years. France has done two wars in the last 3 years (Lybia, Mali and still do stuff in Afganistan). My country is not the best country in the world but we did not end up with some terrible thing like Guantanamo ... I would say the same about many others european countries and it should be the same for USA. If you believe in human rights and dignity, what ever enemy you have to fight, you should not forget the values you are fighting for.
