Peacekeeping and humanitarian law policy – Ambassador Rosemary DiCarlo expressed the support of the United States in implementing the “New Horizon Project,” which attempts to better “anticipate challenges to peacekeeping missions.” Furthermore, the United States called for clearer mandates for Peace Keeping Operations (PKO’s) by including “specific benchmarks whenever possible,” which would “greatly enhance the capacity of the UN to effectively undertake complex peace operations and to review those operations once undertaken.”  The Ambassador also encouraged a greater effort from the UN member states as a whole to train and equip PKO’s to meet increasing demands. Later, Ambassador Susan E. Rice reiterated the need to strengthen the “capacity of the organization to engage effectively in complex peace operations, at a time when the burdens and challenges placed on the institution are greater than ever.”  Similarly, to assist and protect the civilians caught in conflicts, the United States claimed to be “deeply committed to supporting and advancing international humanitarian law.”  In order to uphold this commitment, the international community has specific tasks it must undertake: “preventing conflicts, in the first place, keeping existing conflicts from escalating to mass atrocities, acting early and decisively when they occur, and ensuring that peace-building and post-conflict assistance consolidates peace durably once the conflict ends.”  Lastly, Rice confirmed the necessity of PKO’s to end violations of international humanitarian law and to safeguard civilians.
Iran – Ambassador Susan E. Rice took the President’s stance on concern over Iran’s nuclear program, claiming that the U.S. “will look at what is necessary and appropriate with respect to maintaining pressure towards that goal of ending Iran’s nuclear program.”  She also confirmed support of the Security Council’s obligations on Iran, and encouraged direct diplomacy while continuing work with the Security Council. Similarly, the U.S. encouraged the Iran Sanctions Committee to “redouble its efforts to ensure full and robust implementation of Security Council resolutions 1737, 1747, and 1803.” 
Israel & Palestine – The United States policy, following the recent humanitarian crisis in Gaza, dictates the need for a ceasefire, stating that the US would “work diplomatically and through other means to try to support efforts to ensure that the cease-fire is lasting, and in that context for border crossings to be open and be available for humanitarian as well as day-to-day economic development imperatives.”  Later, Ambassador Susan E. Rice claimed that the Palestinian civilians required “urgent humanitarian and reconstruction assistance.”  She also called on Israel to investigate claims of humanitarian abuse made by Palestinians. Lastly, President Obama’s preference for a two state solution (as described in Security Council Resolution 1850) was reiterated.
Darfur – A priority was placed on civilian protection first and foremost. As a result, the United States will focus on “effective efforts to support the full and complete deployment of UNAMID so that there is the capacity on the ground to begin to effect that civilian protection.”  Several weeks later, Ambassador Rice expressed the United States’ support of the International Criminal Court when they issued a warrant for Sudanese President Bashir’s arrest and also of UN Security Council Resolution 1593, which “requires the Government of Sudan and all other parties to the conflict to cooperate fully with the ICC and its prosecutor.”  Rice also stated that “no one should use the ICC’s decision as a pretext to incite or launch violence against civilians or international personnel.”  After Bashir expelled humanitarian aid groups, the U.S. committed itself to greater efforts “with others to try to avert a deeper humanitarian crisis.”
