2026 Surge in Nuclear Weapons Spending and Heightened Diplomatic Tensions
6/9/2026, 9:24:41 AM
Record Nuclear Expenditure in 2025
A report by the International Campaign to Abolish Nuclear Weapons (ICAN) shows that total spending by the nine nuclear-armed states rose 19 % in 2025 to $119 billion, the highest level since the group began tracking expenditures in 2020. The United States accounted for $69.2 billion, outspending all other states combined and posting the largest year-over-year increase (22 %).
Modernisation Drives the Arms Race
The Stockholm International Peace Research Institute (SIPRI) confirms that the United States and Russia together hold roughly 83 % of the world’s deployable warheads, while China’s arsenal grew to about 620 warheads—its fastest expansion. New delivery systems, such as Russia’s Sarmat ICBM and China’s expanding missile stockpiles, are cited as evidence of a broader shift from disarmament to modernisation.
Principal Actors and Their Positions
- United States – Pursues a record-high nuclear budget and, through Vice President JD Vance, reiterates a policy of seeking a nuclear agreement with Iran irrespective of Israel’s stance.
- North Korea – Kim Yo Jong, the sister of leader Kim Jong Un, declares the country’s nuclear status “absolutely nonnegotiable” and vows to continue “self-defensive nuclear war deterrence.”
- China – President Xi Jinping’s first visit to Pyongyang in seven years aims to reinforce ties with a regime that rejects denuclearisation.
- Iran – Engaged in stalled talks with the United States; the U.S. is circulating an IAEA draft resolution demanding precise accounting of enriched uranium remaining after 2025 strikes.
Spending and Warhead Statistics
- Total nuclear warheads (January 2026): 12 187, with 9 745 in active military stockpiles.
- Deployed warheads: ~4 012, of which ~2 200 are on high alert, primarily in the United States and Russia.
- Nuclear-armed states’ 2025 spending: United States $69.2 billion, China $13.5 billion, United Kingdom $12.6 billion, Russia $9.5 billion.
Official Statements & Responses
ICAN’s report frames the spending surge as a reversal of post-Cold-War demobilisation. The United States’ draft IAEA resolution calls for “precise information on nuclear material accountancy… without delay,” while avoiding a UN Security Council referral. Kim Yo Jong’s statements, issued through the Rodong Sinmun, reject any external pressure to renounce nuclear status.
Criticism & Opposition
SIPRI researcher Hans Kristensen warns that “the evidence is growing that the nuclear weapon states are sidelining… their disarmament commitments.” Russia’s IAEA ambassador counters the U.S. draft, stating “it was exactly the United States who undermined this cooperation.” South Korean President Lee Jae Myung stresses that “North Korea continues to produce nuclear material as we speak,” urging a realistic short-term moratorium.
Conflicting Reports & Gaps
Estimates of Iran’s remaining enriched uranium vary: the IAEA cites 440.9 kg at 60 % enrichment (enough for ~10 weapons), while U.S. officials have not disclosed verification results. Warhead counts differ between SIPRI (12 187 total) and national disclosures, leaving the exact size of each arsenal uncertain.
What’s Next
- June 8-9: President Xi’s summit in Pyongyang is expected to address, at minimum, economic cooperation; nuclear dialogue remains unlikely.
- July 4: The U.S. Department of Energy aims for three advanced reactors to achieve criticality, reflecting a broader nuclear-technology push.
- IAEA Board: The United States will seek support for its draft resolution; outcome will influence the trajectory of U.S.–Iran negotiations.
- Budget Outlook: All nine nuclear powers have announced multi-year funding plans that could sustain or increase spending through the 2030s.
