Can the French supply enough materiel, especially tanks?
In a hot war situation, tanks or airplanes are not a priority in logistics or supplies. Ammunitions and spare parts are...
You need severals weeks to have a tank sent from France to be ready on the israeli front. You need to put the tank on a ship but when it is received, you need to "acclimate" it for desert use.
And when a tank or a plane is destroyed, the crew is probably dead or wounded. So any new tank is of no use because you need months go train a new crew, when I was draft in the french army, 7 months were the minimum to be operationnal for a tank crew.
During Kippour War, the US planes were directly used by Tsahal airforce after arriving in Israel. Most of the heavy equipment was deliver after the war and was use as replacements for destroyed equipment.
In ATL 1967, French help will limited by the number of large transport aircrafts available in the French airforce. In 1973, US airforce have plenty of C130 and some new C5 and when these planes fligh to Israel, they were protected by US aircraft carriers. Again, the french had only an available limited support.
