In the newly released archive of 13 million pages by CIA, a report under the title France and the Arab-Israeli crisis was monitoring the French moves in the extremely unstable Middle East, especially after the rising tension in the Arab-Irsaeli relations during the Six-Day War.
Perhaps the most impressive in the report, is that it refers to specific powerful banking and business names that were pushing for the lift of the embargo, like the House of Rothschild and Marcel Dassault. The report also refers to the role of Georges Pompidou, Prime Minister of France at the time, who has been "former Director General of the House of Rothschild", as also mentioned:
On 5 June Paris publicly announced a decision made on 2 June – before the opening of Middle East hostilities - to place a total embargo on arms to all countries involved in the conflict. This particularly affected Israel, since its armed forces relied heavily on French armaments.
On 8 June the policy was to be modified to permit the shipment of spare parts but not offensive weapons, reportedly as a result of Premier Pompidou's reminder to De Gaulle that all armaments contracts with Israel included a clause to supply spares for 10 years. The embargo is officially still in effect, but there has been welter of conflicting information on whether it is being observed. All indications are that shipment of spare parts was resumed after a short break in early June and is continuing.
On the matter of offensive weapons, Israel is almost certainly receiving some equipment which falls in this category. Powerful banking and business circles, such as the House of Rothschild and Marcel Dassault, have put pressure on French officials, and particularly on Premier Pompidou (former Director General of the House of Rothschild), to lift the embargo. The Dassault firm argued that French manufacturers would lose out completely in the future as suppliers of arms to friendly nations if they were not able to resupply in time of real need.
There have been rumors that Israel cancelled its arms contracts with France. Our best judgment is that there have been discussions of cancellation but that no decision had been taken.
The report also concentrates on the attempt of France to play a major role in the future developments in Middle East, therefore, De Gaulle's attempt to maintain relative balance:
Efforts to extend French influence in the Middle East have been given a boost by careful cultivation of the Arabs during the conflict, and there have been indications that some Arab states would favor France as a mediator in the conflict. [...] France is the only major power which is not linked with either of the combatants or their big power supporters – a point which Paris unfailingly makes. [...] At this point, De Gaulle's immediate concern is to keep Franco-Soviet relations from deteriorating and to prevent the “super-powers” from negotiating without France. [...] De Gaulle might still hope that a threat to cut off even the present supply of arms and spare parts would give him some leverage on Israel which could be used to lead it to moderate its demands for a settlement. Over the longer run, France might under certain circumstances lift its embargo.
