The French benefitted hugely from inherited infrastructure investment from the USAF being required to withdraw from France. In 1966, the USAF had several air bases in France - many of which the USAF had built up from scratch for the jet era after the start of the Cold War.
For instance, at Toul-Rosieres AB, the 26 TRW was in the process of converting from the RF-101C to RF-4C and at Laon-Couvron AB the 66 TRW was operating the RF-101C. The 26 TRW relocated to Ramstein AB and the 66 TRW relocated to RAF Upper Heyford.
The French AF then moved F-100s into Toul and the French Army moved into Laon with Pluton tactical nuclear missiles.
Earlier. the French had also caused much nugatory work and expense for the USAF by requiring the relocation of nuclear strike assets out of the county. For instance, in July 1956, the 50 TFW moved into Toul from Hahn AFB, West Germany with the 74 x F-86H. From May 1957, 50 TFW started converting to 75 x F-100D/F with a primary mission of tactical nuclear strike but by December 1959 were relocated back to Hahn AFB !
