The UN Security Council has demanded that Iran suspend its nuclear enrichment activities in multiple resolutions.[387][388] The United States has said the "central bargain of the NPT is that if non-nuclear-weapon states renounce the pursuit of nuclear weapons, and comply fully with this commitment, they may gain assistance under Article IV of the Treaty to develop peaceful nuclear programs". The U.S. has written that Paragraph 1 of Article IV makes clear that access to peaceful nuclear cooperation must be "in conformity with Articles I and II of this Treaty" and also by extension Article III of the NPT.[389] Rahman Bonad, Director of Arms Control Studies at the Center for Strategic Research at Tehran, has argued that demands to cease enrichment run counter to "all negotiations and discussions that led to the adoption of the NPT in the 1960s and the fundamental logic of striking a balance between the rights and obligations stipulated in the NPT."[390] In February 2006 Iran's foreign minister insisted that "Iran rejects all forms of scientific and nuclear apartheid by any world power," and asserted that this "scientific and nuclear apartheid" was "an immoral and discriminatory treatment of signatories to the Non-Proliferation Treaty,"[391] and that Iran has "the right to a peaceful use of nuclear energy and we cannot accept nuclear apartheid.
