On June 22, 2010, Under Secretary of State for Political Affairs William Burns testified before the U.S. Senate Foreign Relations Committee. Under Secretary Burns' testimony included comments on U.S policy towards Iran after the passage of United Nations Security Council (UNSC) Resolution 1929.
He said, "[A]merican policy is straightforward. We must prevent Iran from developing nuclear weapons. We must counter its other destabilizing actions in the region and beyond. And we must continue to do all we can to advance our broader interests in democracy, human rights and development across the Middle East."
When speaking about UNSC Resolution 1929, Under Secretary Burns said, "For the first time, it bans significant transfers of conventional weapons to Iran. For the first time, 1929 bans all Iranian activities related to ballistic missiles that could deliver a nuclear weapon. For the first time, it imposes a tough framework of cargo inspections to detect and stop Iran's smuggling and acquisition of nuclear materials or other illicit items."
