<li><font size="4">The overall JCPOA limit was 300 kg of UF₆ (≈202.8 kg uranium mass) at ≤3.67%. Iran was well below this and had no higher-enriched material under the deal.</font></li>

<p dir="auto" style="white-space-collapse: preserve;"><font size="4">Military attacks began on/around 13 June 2025. The IAEA’s last verified/estimated figures before that (drawing on Iranian declarations, inspections up to 12 June, and production estimates) showed:</font></p>
<ul dir="auto">
<li><font size="4"><strong>Total enriched uranium stockpile</strong>: ≈ <strong>9,875 kg</strong> (uranium mass; ≈9,040 kg as UF₆ + ~834 kg in other forms).</font></li>

<li><font size="4">Up to <strong>60% U-235</strong>: ≈<strong>441 kg</strong></font></li>
</ul></li>
<li><font size="4">The 60% material (near weapons-grade; only a short further enrichment step to ~90%) alone was theoretically enough, if further enriched, for multiple bombs by common IAEA/yardstick estimates (~42 kg of 60% material ≈ one bomb’s worth of potential).</font></li>
</ul>
<h3 dir="auto"><font size="4">Comparison</font></h3>
<ul dir="auto">
<li><font size="4"><strong>Quantity</strong>: <u>From ~124 kg of ≤3.67% material in May 2018 to nearly <strong>10 tonnes</strong> total enriched uranium</u> (of which hundreds of kg were at 20% and 60%) by mid-June 2025 — an increase of roughly <strong>80-fold</strong> in total enriched uranium mass.</font></li>
<li><font size="4"><strong>Quality/enrichment level</strong>: 2018 material was all low-enriched reactor-grade (≤3.67%). By 2025 Iran had large holdings at 5%, significant 20%, and a substantial near-weapons-grade (60%) stockpile that did not exist under the JCPOA.</font></li>
<li><font size="4"><strong>Context</strong>: After the 2018 U.S. withdrawal and reimposition of sanctions, Iran gradually exceeded JCPOA limits starting in 2019 (higher enrichment, larger stockpiles, more advanced centrifuges). By early–mid 2025 the program had expanded dramatically. Post-June 2025 strikes and reduced IAEA access, the exact status/location of the pre-war stockpile became unverified.</font></li>

<p dir="auto" style="white-space-collapse: preserve;"><font size="4">These figures are uranium mass (not UF₆ mass) from IAEA reports and consistent secondary analyses. “Amount of uranium-235” in public discussion usually refers to the mass of the <em>enriched uranium product</em> (which contains the stated % of the isotope U-235), not the pure isotope mass alone. Pure U-235 content would be a fraction of the above totals (e.g., roughly 3.67% of the 2018 stockpile vs. a weighted average of the much higher 2025 percentages).<span class="gmail_default" style="font-family:arial,helvetica,sans-serif">"</span></font></p><p dir="auto" style="white-space-collapse: preserve;"><font size="4"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">===</span></font></p><p><b style="background-color:transparent;font-family:tahoma,sans-serif;font-size:large"><span class="gmail_default"><u>Me</u>: </span><span style="background-color:transparent">Is there any evidence that Iran violated the JCPOA (also called the Iran nuclear deal) before May 8, 2018?</span></b></p><p><b style="background-color:transparent"><span style="background-color:transparent"><span class="gmail_default" style=""><font size="4" style=""><font face="arial, helvetica, sans-serif"></font><u style=""><font face="tahoma, sans-serif">Grok</font></u><font face="arial, helvetica, sans-serif">: "</font></font></span></span></b><font size="4"><strong style="background-color:transparent"><u>No significant evidence of material violations of the JCPOA’s nuclear restrictions by Iran before May 8, 2018</u>.</strong><span style="background-color:transparent"> The International Atomic Energy Agency (IAEA), which was responsible for verifying and monitoring Iran’s compliance, repeatedly confirmed that Iran was implementing its nuclear-related commitments under the deal from Implementation Day (January 16, 2016) through the period leading up to the U.S. withdrawal.</span></font></p>
<h3 dir="auto"><font size="4">Key points from IAEA and official assessments</font></h3>
<ul dir="auto">
<li><font size="4"><strong>Quarterly IAEA reports</strong> (from 2016 through the May/June 2018 report covering the period around the withdrawal) consistently stated that Iran was abiding by the limits on uranium enrichment levels (≤3.67% U-235), enriched uranium stockpile size (≤300 kg UF₆ or equivalent), centrifuge numbers and types, heavy water stockpile (≤130 metric tons), research reactor redesign, reprocessing bans, and related restrictions. Access and monitoring under the Additional Protocol and JCPOA-specific measures were also ongoing.</font></li>
<li><font size="4">The IAEA report finalized around late May 2018 (the first after the U.S. announcement) reaffirmed compliance on these points, with the low-enriched uranium stockpile at about 123.9 kg (well under the limit) as of mid-May 2018.</font></li>
<li><font size="4">Contemporary statements from the U.S. State Department (under both Obama and early Trump administrations), the EU, other JCPOA participants (UK, France, Germany, Russia, China), and the UN Security Council framework under Resolution 2231 aligned with the IAEA’s findings of Iranian compliance with the nuclear terms up to that point.</font></li>
</ul>
<h3 dir="auto"><font size="4">Minor/temporary issues sometimes cited</font></h3>
<p dir="auto" style="white-space-collapse: preserve;"><font size="4">Iran briefly exceeded the heavy water stockpile limit of 130 metric tons on two occasions in 2016 (shortly after Implementation Day). In both cases, the excess was small, and Iran promptly shipped out enough material to return below the limit. These were resolved without being treated as ongoing or significant non-compliance by the IAEA or the JCPOA Joint Commission.</font></p>
<p dir="auto" style="white-space-collapse: preserve;"><font size="4">Other critiques raised by the Trump administration or critics (e.g., claims about the “spirit” of the deal, ballistic missiles, regional activities, or alleged intimidation of inspectors) fell outside the JCPOA’s specific nuclear restrictions and verification scope. T<u>he IAEA did not report that Iran was blocking required access or failing its core nuclear commitments prior to May 2018</u>. Some later U.S. statements after withdrawal retroactively characterized Iran’s pre-deal history or the deal’s structure itself as problematic, but these do not constitute evidence of JCPOA violations during the period the deal was being implemented by Iran.</font></p>
<p dir="auto" style="white-space-collapse: preserve;"><font size="4">In short, the authoritative verification body (IAEA) and the other parties to the agreement <u>found Iran in compliance with the JCPOA’s nuclear provisions before the U.S. withdrawal</u>. Iran’s clear, successive breaches of the enrichment and stockpile limits began in mid-2019, after the U.S. exit and the reimposition of sanctions.<span class="gmail_default" style="font-family:arial,helvetica,sans-serif">"</span></font></p><p dir="auto" style="white-space-collapse: preserve;"><font size="4"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">===</span></font></p><p dir="auto" style="white-space-collapse: preserve;"><font size="4" face="tahoma, sans-serif"><b>Don't believe <span class="gmail_default">G</span>rok<span class="gmail_default">?
