That's your opinion, not theirs.
Show me how I'm wrong. It's after WWII. Germany has twice in a few decades attempted to overrun Europe, causing millions of deaths and devastating vast portions of the continent. The US goes back home, leaving no military presence.
You're the leadership of France. What do you do?
1. Build a massively expensive nanny state, assuming there will be no further problems from Germany and Italy. After all, they only did it twice.
2. Beg the US to maintain a military presence in the region to help contain any potential aggression, since the US is emerging as one of the world's true super powers.
3. Rebuild your military to be as strong as possible to ensure that you will never be overrun like you just were.
Go on, pick anything other than 3 and make a logical argument for it. prove me wrong.
