Until September 8, all senators had committed to the agreement, with 42 supporting 40 Democrats and 2 independents and 58 against (54 Republicans and 4 Democrats).  Senators were able to support the resolution of disapproval in the Senate by effectively filtering it, rendering it unnecessary for Obama to veto a resolution of disapproval.  But this was only possible if at least 41 voted in favour, and several senators who supported the agreement, including Coons, ”suggested that they would prefer a vote on the agreement rather than block it completely.”  Abbas Milani and Michael McFaul wrote, ”Among those who support this agreement, there are moderates in the government, many opposition leaders, a majority of Iranian citizens and many in the Iranian-American diaspora – a disparate group that has rarely agreed on anything.”  Within the government, Rohani and Foreign Minister Javad Zarif, who negotiated the agreement, are ”now the loudest in defense against Iranian hawks.”  Former Presidents Akbar Hashemi Rafsanjani and Mohammad Khatami, as well as moderates in Parliament, also support the agreement.  The agreement is also supported by the most prominent opposition leaders, including Mir-Hossein Mousavi, the 2009 presidential candidate, who was placed under house arrest for his role as leader of the Green Movement.  In addition, the JCPOA does not accept any of our options to prevent Iran from acquiring a nuclear weapon. As I have repeatedly pointed out, my Government will take all necessary measures to achieve this goal, including military means. If Iran tries to move toward a nuclear weapon, all options available to the United States – including the military option – will remain available for the duration of the agreement and beyond.  On September 6, 2015, former Foreign Minister Colin Powell spoke out in favour of the Iran nuclear deal and declared it ”a good deal.”  Powell said that several provisions accepted by Iran – such as the reduction of centrifuges and uranium reserves and the agreement to shut down its plutonium reactor – were ”remarkable changes” that halted Iran`s path to a nuclear weapons program. Powell also defended the revision provisions of the agreement and said, ”I think a very strong verification system has been put in place.”  In September 2009, U.S. President Barack Obama revealed the existence of an underground enrichment site in Fordow, near Qom, and said, ”Iran`s decision to build another nuclear power plant without notifying the IAEA poses a direct challenge to the basic pact at the heart of the non-proliferation regime.”  Israel has threatened to take military action against Iran.  The Roman Catholic Church voted in favour of the agreement. In a July 14, 2015 letter to Congress, Archbishop Oscar Canté, chairman of the Committee for International Justice and Peace of the United States Conference of Catholic Bishops, wrote that the JCPOA was ”an important agreement” that ”marks progress in nuclear non-proliferation around the world.”   Catholic bishops in the United States ”will continue to ask Congress to approve the outcome of these intense negotiations, as the alternative leads to armed conflict, an outcome that deeply worries the Church.”   One of the points of disagreement between supporters and opponents of the JCPOA is the consequences of withdrawing an agreement and whether a renegotiation of the agreement is a realistic option. Senator Chuck Schumer, Democrat of New York, an opponent of the agreement, called the United States.
