Jacques nuclear weapons are like balls, just because you have them doesn't mean you'll use them.
If the Frogs had them at the time they would have used them at Dien Bien Phu.
They asked Ike at that time to use ours to aid them. Ike refused.
Dien Bien Phu fell and the French had to stop pretending to be relevant.
That incident was a major reason for France deciding to build their own nuclear umbrella.
Thank God the French didn't have Nukes.
