问答题In 1945, in the shadow of a world war and the face of an uncertain future, 51 founding nations joined in common purpose to establish the United Nations and codify its mission to maintain international peace and security, encourage global cooperation, and promote universal respect for human rights. Nearly seven decades later, we once again find ourselves at a pivotal moment in history— a crossroads between conflict and peace, disorder and integration, hatred and dignity—dealing with new challenges that require a united response. As we confront these global problems in an increasingly interconnected world, the United Nations remains as necessary and vital as ever. On United Nations Day, we recognize the important role the United Nations continues to play in the international system, and we reaffirm our country’ s commitment to work with all nations to build a world that is more just, more peaceful, and more free.【】The United Nations fosters international cooperation and enables progress on the world’ s most immediate threats and critical long-term challenges. From addressing climate change and eradicating poverty to preventing armed conflict and halting the proliferation of weapons of mass destruction, the work of the United Nations supports our shared pursuit of a better world. In this spirit of mutual interest and mutual respect, the international community must continue to find common ground in the face of threats to the prosperity and security of all our nations.【】Across the globe, United Nations personnel put their lives on the line to give meaning and action to the simple truths enshrined in the Nations Charter. Today, U. N. humanitarian staffs are providing lifesaving relief to those trapped by conflict; U. N. peacekeepers are protecting civilians against threats from extremists andother violent groups; and U. N. health workers are helping to bring Ebola under control in West Africa and deliver critical medicines to people around the world.
