BS, the French Force de Dissuasion was not operational until 1964.
They were in the integrated command structure at that time and had staff at HQ SAC. In 1965, when De Gaulle left the ICS the French staff were still at Offutt but their status had changed to observer. We were not told exactly how this would work. I guess it meant they would not be assigned SIOP targets but were given TOT windows.
