 A BILL

To authorize the President to take actions to ensure Israel is prepared 
 for all contingencies if Iran seeks to develop a nuclear weapon, and 
 for other purposes.

 Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

 This Act may be cited as the ``Bunker Buster Act of 2025''.

SEC. 2. FINDINGS.

 Congress finds the following:

    (1) The United States Nuclear Regulatory Commission defines 
 ``high-enriched uranium'' as uranium enriched to at least 20 
 percent uranium-235.

    (2) Under the 2015 Joint Comprehensive Plan of Action, Iran 
 agreed to refrain from producing enriched 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 April 16, 2021, Dr. Salehi told the state television 
 that Iran had begun enriching uranium to 60 percent.

    (5) On July 14, 2021, the former President of Iran, 
 President Hassan Rouhani, said during a press conference that 
 Iran has the knowledge and ability to enrich weapons-grade 
 uranium at 90 percent.

    (6) According to an International Atomic Energy Agency

    (IAEA) report, as of May 11, 2024, Iran has 142.1 kilograms 
 (313.2 pounds) of uranium enriched up to 60 percent, an 
 increase of 20.6 kilograms (45.4 pounds) since the last report 
 by the United Nations watchdog in February. Uranium enriched at 
 60 percent purity is just a short, technical step away from 
 weapons-grade levels of 90 percent. Iran's overall stockpile of 
 enriched uranium stands at 6,201.3 kilograms (1,3671.5 pounds), 
 which represents an increase of 675.8 kilograms (1,489.8 
 pounds) since the IAEA's previous report.

    (7) The current stockpile is enough to make several nuclear 
 bombs according to the criteria the IAEA uses to make such 
 determinations.

    (8) Reports indicate the Iran may be constructing new 
 facilities to help expand its nuclear program.

    (9) In June 2024, the IAEA elected to censure Iran for its 
 violation of international responsibilities under its nuclear 
 agreement and demanded its cooperation, including the 
 readmittance of inspectors and the restoration of camera 
 surveillance at nuclear sites.

    (10) In June the IAEA announced Iran is installing 1,400 
 new advanced centrifuges at its Fordow facility.

    (11) Since October 7, 2023, Israel has been at war with 
 Hamas in the Gaza strip, which has used Iranian funding and 
 direction to target the Jewish state.

    (12) Hamas continues to hide within civilian 
 infrastructure, fire rockets at humanitarian crossings, and 
 steal international aid and resources that are only further 
 hurting the Palestinian civilians. Hamas has built tunnels 
 under United Nations Relief and Works Agency for Palestine 
 Refugees in the Near East

    (UNRWA) buildings, including a large 
 data center under UNRWA's Gaza base, and stores weapons in 
 UNRWA schools.

    (13) As of June 2024, Ansarullah, or otherwise known as the 
 Houthis, have launched at least 60 attacks at ships. They have 
 seized 1 vessel, killed 4 sailors, and sunk 2 ships since 
 November 2023. The Houthis have also launched drones, missiles, 
 and mortars toward Israel and at United States and its allies. 
 The Houthis operate with Iranian funds.

    (14) Since October 7, 2023, Hezbollah has launched over 
 5,000 rockets, missiles, and drones at Israel. Iran has, 
 provided Hezbollah with more than 100,000 missiles and rockets.

    (15) Iran is expanding its missile capacity and 
 weaponization program to further assist their proxies across 
 the region.

    (16) On June 12, 2025, 60 days had lapsed without an 
 agreement in diplomatic negotiations to prevent Iran from 
 attaining a nuclear weapon.

    (17) On June 12, 2025, IAEA board declared Iran in 
 violation of its non-proliferation obligations.

    (18) On June 13, 2025, Israel launched a coordinated series 
 of strikes against Iranian military and government targets in 
 efforts to disrupt Iran's development of a nuclear weapon based 
 on Israeli intelligence assessment that Iran had taken steps 
 putting them closer to achieving nuclear latency.

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 enriched 
 uranium, including through engagement in multilateral 
 diplomatic initiatives;

    (2) ensure that Israel and other allies are prepared for 
 all contingencies if Iran pursues development 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. ACTIONS TO ENSURE ISRAEL IS PREPARED FOR ALL CONTINGENCIES IF 
 IRAN SEEKS TO DEVELOP A NUCLEAR WEAPON.

    (a) In General.--Subject to the preliminary conditions described in 
subsection

    (b) , the President is authorized to take the actions

    (b) Preliminary Conditions.--The President may exercise the 
authority of subsection

    (a) only if the President first determines and 
certifies to Congress that it is vital to the national security

        (B) are met.

            (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

 underground nuclear infrastructure or facilities; and
            (iv) a dual key control system is in place
