uranium enriched to at least 20 percent uranium– 
235. 
(2) Under the 2015 Joint Comprehensive Plan 
of Action, Iran agreed to refrain from producing en-
riched uranium containing more than 3.67 percent 
uranium–235 for 15 years. 
(3) On January 13, 2019, the head of the 
Atomic Energy Organization of Iran, Dr. Ali Akbar 
Salehi, told the Fars News Agency, ‘‘If we want to 
come out of the nuclear deal and produce, within 
four days we could start our 20 percent.’’. 
(4) On June 17, 2019, the spokesman for 
Iran’s 
Atomic 
Energy 
Organization, 
Behrouz 
Kamalvandi, suggested that Iran’s enrichment could 
reach up to 20 percent. 
(5) On April 16, 2021, the head of the Atomic 
Energy Organization of Iran, Dr. Ali Akbar Salehi, 
told the state television that Iran had begun enrich-
ing uranium to 60 percent. 
(6) On July 14, 2021, the former President of 
Iran, President Hassan Rouhani, says during a 
press conference that Iran has the knowledge and 
ability to enrich weapons-grade uranium at 90 per-
cent.

(7) On September 7, 2021, the International 
Atomic Energy Agency warned in their quarterly re-
port of the knowledge gained by Iran about ad-
vanced centrifuge performance and higher-level en-
richment that cannot be fully reversed. The report 
showed that the stockpile of 60 percent enriched 
uranium grew from 2.4 kilograms in May to 10 kilo-
grams. It also indicated Iran reconfigured its 60 
percent production lines at Natanz and appears to 
be enriching to that level more efficiently and con-
sistently. 
SEC. 3. SENSE OF CONGRESS. 
It is the sense of Congress that the United States 
should— 
(1) seek to extend the limitations on Iran’s en-
riched uranium, including through engagement in 
multilateral diplomatic initiatives; 
(2) ensure that Israel and other allies are pre-
pared for all contingencies if Iran pursues develop-
ment of a nuclear weapon; 
(3) send a clear signal to Iran that development 
of a nuclear weapon will never be tolerated; and 
(4) reaffirm the United States commitment to 
deter Iranian nuclear development with a credible 
military threat.

SEC. 4. STUDY AND REPORT. 
(a) STUDY.—The President, acting through the Sec-
retary of Defense, shall seek to conduct a study with the

qualitative military edge (as such term is defined in sec-
tion 36(h)(3) of the Arms Export Control Act (22 U.S.C. 
2776(h)(3))) and national security, including an Iranian 
nuclear weapon. Such study shall include an analysis of 
gaps in Israel’s security requirements, including infra-
structure, munitions, intelligence sharing, satellites, and 
the extent to which the transfer of United States ordnance 
to Israel would advance the national interests of both 
countries. 
(b) REPORT.—Not later than 180 days after the date 
of the enactment of this Act, the President shall transmit 
to Congress a report that contains the results of the study 
described in subsection (a). 
(c) FORM.—The report referred to in subsection (b) 
shall be submitted in unclassified form but may include 
a classified annex.

the request of the Government of Israel, to ensure Israel 
is prepared for all contingencies if Iran seeks to develop

dent first determines and certifies to Congress that—

(2) it is vital to the national security interests 
of the United States to do so. 
(c) ACTIONS DESCRIBED.—The actions described in 
this subsection are the following: 
(1) To provide for the construction of infra-

(II) has modified its implementation 
of the NPT Safeguards Agreement (includ-
ing modified Code 3.1); or 
(III) as determined by the President, 
has reduced access of inspectors of the 
Agency in such a manner so as to be prej-
udicial to the Agency’s ability to provide 
confidence as to the non-diversion of de-
clared nuclear material and absence of 
undeclared nuclear activities; 
(ii) it is vital to the national security of the 
United States to do so; 
(iii) Israel has no other means to achieve 
a mutual national security objective of destroy-
ing Iran’s underground nuclear infrastructure
