Answer:
The two choices that would answer the question: which two of the following ideas related to international relations and security did the Allies support and promote during World War 2 are: A: Nations must cooperate to bring about and maintain peace, and C: Nations must not wage wars or commit war crimes in a desire to control other nations.
Step-by-step explanation:
The reason for these two being the answers comes from the Joint Four-Nation Declaration, signed during the Conference of Moscow, in 1943. In this Conference, and especially the Declaration, aside from discussing how the Allies should handle the war, and events that would come after the defeat of the Axis powers, particularly Germany, the Four great nations: United Kingdom, the United States, the Soviet Union and China, declared, among other things, these two points. In total, the Declaration held 7 specific points. It is thanks to this Declaration, that the four powers recognized the need to create a joint organization, which was the seed for the creation of the United Nations, later on.
