translate English to French: It was indeed incumbent on the international community to strengthen the rule of law both nationally and internationally, since it could be argued that its erosion or collapse was at the basis of existing conflicts within and between nations.
Il incombe effectivement à la communauté internationale de renforcer l'état de droit à ces deux niveaux, car on pourrait dire que son érosion ou son effondrement est la cause des conflits internes et internationaux actuels.
