In this charter, the leaders practically assure the world that action is needed, that both Britain and the U.S commit themselves to achieving what it right and necessary for the wellfare of the entire world and their wish for peace, and the ensuring of the rights that all people should expect. They are assuring the world that Germany will be defeated by their joint power. This is why the answer is the one above.
