Доброй всем ночи. Интересуюсь, удачно ли я подобрала перевод для следующих сочетаний:

Заранее большое спасибо

The dissolution of the European empires by the late 1960s marked the end of the period of European predominance in the world that had lasted since the mid-nineteenth century. The creation of a mass of new, independent states transformed the world balance of power. It led to the emergence of a number of 'security complexes' - regional security regimes with their own dominant and subordinate powers and their own conflicts. Until the mid-1940s there were only two security complexes in the world - Europe and Asia - and the former could affect the whole world. It was not until December 1941 that the two complexes were brought together with the attack by Japan (the dominant regional power in Asia) on the United States and the European powers
