Martin regards these failures as betrayals , and two stand out : the unwillingness of the British and Americans to enforce the Versailles Treaty , and the refusal of French leaders to acknowledge the depth of the economic problems facing France and the sacrifices required to overcome them .

The cooperation of the military is essential to the universalisation of the Ottawa Treaty , and the ICRC is focusing much activity in this area . the demilitarization provisions in the Antarctic Treaty , and the minerals prohibition in the Protocol . The groundwork for common defence is in the Maastricht Treaty , and the Commission as guardian of the treaties has shown its determination to further this programme .
