The world is experiencing multiple active conflicts with direct or indirect involvement of major powers, each carrying significant escalation potential:

• Russia-Ukraine War:

  • The conflict remains protracted, with no diplomatic resolution and active military operations. Russia’s nuclear doctrine (2024) lowers the threshold for nuclear use, and NATO’s support for Ukraine risks direct clashes.
  • Escalation risks include NATO involvement, tactical nuclear use, and regional spillover.

• Israel-Iran Conflict:

  • Direct military confrontation between Israel and Iran has intensified, with U.S. involvement and retaliatory threats from Iran. Iran’s uranium enrichment at 83.7% purity places it weeks away from weapons-grade material.
  • Escalation risks include direct U.S.-Iran conflict, maritime disruption, and nuclear breakout.

• Taiwan Strait Tensions:

  • China has intensified military drills around Taiwan, including blockade simulations. The U.S. maintains a deterrence posture, but accidental clashes or miscalculation could trigger a major conflict.
  • Escalation risks include blockade or invasion, alliance activation, and regional spillover.

• North Korea:

  • North Korea’s nuclear and missile programs continue to expand, with a first-use doctrine and regular tests. A provocation (e.g., nuclear test) could prompt U.S. or South Korean retaliation, risking Chinese involvement.

The global nuclear landscape is more unstable than at any point since the Cold War, with eroding arms-control frameworks, expanding arsenals, and lowered thresholds for use:

• Russia:

  • Doctrine: Russia’s 2024 nuclear doctrine allows nuclear use in response to conventional threats to the state’s existence.
  • Capabilities: Russia possesses ~2,000 tactical nuclear warheads, many deployed and on elevated readiness.
  • Rhetoric: Russian leadership has issued nuclear threats, framing the Ukraine war as existential.

• China:

  • Expansion: China is rapidly expanding its nuclear arsenal, with estimates projecting 1,000 operational warheads by 2030.
  • Doctrine: China maintains a no-first-use policy, but its growing arsenal and hypersonic capabilities introduce new strategic dynamics.

• Iran:

  • Breakout timeline: Iran is 2–4 weeks away from producing weapons-grade uranium, with no active diplomatic channels to constrain its program.
  • Regional implications: An Iranian nuclear weapon could trigger a regional arms race.

• North Korea:

  • First-use doctrine: North Korea has adopted a first-use policy, meaning it could preemptively use nuclear weapons in a conflict.
  • ICBM capabilities: North Korea’s solid-fuel ICBMs can reach the U.S. mainland.

• Arms-Control Collapse:

  • New START expired in February 2026 without replacement, removing the last bilateral nuclear arms-control agreement between the U.S. and Russia.
  • INF Treaty collapsed in 2019, leading to the redeployment of intermediate-range missiles in Europe and Asia.
  • CTBT remains unratified by the U.S. and China, allowing for potential resumption of nuclear testing.

• Escalation Risks:

  • Tactical nuclear use: The most immediate risk is the use of a low-yield tactical nuclear weapon in Ukraine or the Middle East.
  • Miscalculation: Shrinking decision windows (due to hypersonic weapons and AI-driven early warning systems) increase the risk of accidental escalation.
  • Nuclear terrorism: The deterioration of state control over nuclear materials raises the risk of non-state actor use.

Military alliances amplify the risk of escalation by expanding the scope of conflict and creating credibility dilemmas for major powers:

• NATO:

  • Article 5: NATO’s collective defense clause means an attack on one member is an attack on all. A direct clash between Russia and a NATO member could trigger full-scale war.
  • U.S. leadership: The U.S. is the cornerstone of NATO, and its commitment to European defense is being tested by political divisions.
  • Expansion: NATO’s open-door policy has led to Finland and Sweden’s accession, further provoking Russia.

• U.S.-Japan-South Korea Trilateral Pact:

  • Regional deterrence: The U.S. has strengthened military cooperation with Japan and South Korea to counter North Korea and China.
  • Taiwan contingency: Japan’s security interests in Taiwan could draw it into a U.S.-China conflict.

• AUKUS:

  • Indo-Pacific focus: The U.S.-UK-Australia security pact aims to counter China’s naval expansion through nuclear-powered submarines and advanced capabilities.
  • Escalation risk: AUKUS could provoke China and accelerate the regional arms race.

• Collective Security Treaties in the Middle East:

  • U.S.-Israel: The U.S. has reaffirmed its commitment to Israel’s security, including military support and intelligence sharing.
  • Iran-Syria-Hezbollah Axis: Iran’s network of proxies creates a multi-front escalation risk for Israel and the U.S.

• Escalation Dynamics:

  • Alliance credibility: Major powers may escalate conflicts to demonstrate resolve to allies.
  • Entanglement: A conflict in one theater (e.g., Taiwan) could spill over into another (e.g., Korea) through alliance obligations.

The diplomatic environment is characterized by deep mistrust, eroding norms, and a lack of crisis-management mechanisms:

• U.S.-China Relations:

  • Strategic competition: The U.S. and China are locked in a rivalry across military, economic, and technological domains.
  • Diplomatic channels: While high-level dialogues exist, they are not robust enough to manage crises (e.g., Taiwan, South China Sea).
  • Economic decoupling: Sanctions, export controls, and supply-chain restrictions are deepening divisions.

• U.S.-Russia Relations:

  • No diplomatic off-ramps: The war in Ukraine has severed most diplomatic ties, leaving no functional crisis-management channels.
  • Nuclear diplomacy: The collapse of arms-control agreements removes key guardrails against escalation.

• Middle East Diplomacy:

  • Abraham Accords: The normalization agreements between Israel and Arab states are fragile and could collapse under regional escalation.
  • Iran nuclear deal: The JCPOA is dead, and no alternative framework exists to constrain Iran’s nuclear program.

• Multilateral Institutions:

  • UN Security Council: Deadlocked by U.S.-Russia-China rivalry, the UNSC is unable to address major conflicts.
  • G20 and G7: These forums are increasingly divided and unable to provide leadership on global security issues.

• Crisis Management:

  • Hotlines and deconfliction: While military-to-military channels exist, they are not always used effectively.
  • Backchannel diplomacy: Unofficial dialogues are weak or nonexistent in key areas.

Economic factors both constrain and accelerate conflict risks:

• Interdependence as a Constraint:

  • U.S.-China trade: Despite tensions, the U.S. and China remain deeply interconnected, with $600+ billion in annual trade.
  • Energy markets: Global energy supplies are vulnerable to disruptions in the Middle East or Russia, creating shared incentives for stability.

• Sanctions as an Escalation Tool:

  • Russia: Western sanctions have failed to cripple Russia’s economy but have deepened its isolation and increased its reliance on China.
  • Iran: U.S. sanctions on Iran have weakened its economy but strengthened its resistance narrative, increasing regional aggression.
  • Secondary sanctions: The U.S. has threatened secondary sanctions on countries trading with Russia or Iran, risking broader economic conflict.

• Economic Warfare:

  • SWIFT and financial systems: The exclusion of Russian banks from SWIFT demonstrates how financial tools can be weaponized.
  • Supply-chain disruptions: Sanctions and export controls are fragmenting global supply chains and accelerating decoupling.

• Market Volatility:

  • Energy prices: A major disruption in the Middle East could spike oil prices and trigger global recession.
  • Stock markets: Geopolitical shocks could crash global markets, creating economic feedback loops that accelerate conflict.

History provides sobering lessons about how localized conflicts can spiral into global wars:

• World War I:

  • Alliance entanglement: A single assassination triggered a cascade of alliance obligations, leading to global war.
  • Miscalculation: Leaders underestimated the risks of escalation, assuming the war would be short and limited.

• World War II:

  • Expansionist regimes: Unchecked aggression led to wider wars as allies were drawn in.
  • Failure of deterrence: Appeasement policies emboldened aggressors rather than preventing war.

• Cuban Missile Crisis:

  • Nuclear brinkmanship: The world came within minutes of nuclear war due to miscommunication and miscalculation.
  • Crisis management: Backchannel diplomacy and de-escalation were critical to averting catastrophe.

• Cold War Proxy Wars:

  • Indirect conflicts: The U.S. and USSR fought proxy wars that risked direct confrontation.
  • Arms races: Nuclear and conventional arms races created persistent instability.

• Lessons for Today:

  • Alliances can accelerate escalation: Credibility dilemmas may force leaders to escalate to avoid appearing weak.
  • Miscalculation is a constant risk: Shrinking decision windows increase the likelihood of mistakes.
  • Economic interdependence is not a guarantee: Globalization did not prevent WWI or WWII, and decoupling today could increase risks.

The next 12 months represent a period of heightened risk for global conflict, with multiple pathways to escalation and few diplomatic off-ramps. While nuclear deterrence and economic interdependence continue to act as constraints, the convergence of crises in Europe, the Middle East, and the Indo-Pacific creates a volatile systemic environment.

Key Scenarios to Watch:

1. Tactical Nuclear Use in Ukraine or the Middle East:

   • A Russian tactical nuclear strike in Ukraine or an Iranian radiological attack could trigger NATO or U.S. retaliation, leading to rapid escalation.

2. Taiwan Blockade or Invasion:

   • A Chinese blockade or amphibious assault on Taiwan could provoke a U.S. military response, drawing in Japan, Australia, and other allies.
   • Accidental clashes could escalate into direct conflict.

3. Direct U.S.-Iran War:

   • A major U.S. or Israeli strike on Iranian nuclear facilities could provoke Iranian retaliation against U.S. bases or shipping, leading to a broader regional war.

4. NATO-Russia Clash in Europe:

   • A direct clash between Russian and NATO forces could trigger Article 5 and escalate into full-scale war.

5. North Korean Provocation:

   • A North Korean nuclear test or missile strike could provoke U.S. or South Korean retaliation, risking Chinese intervention.

Mitigating Factors:

• Nuclear Deterrence: The risk of mutual assured destruction continues to constrain major-power conflict.
• Economic Interdependence: Global supply chains and energy markets create shared incentives for stability.
• Diplomatic Efforts: Backchannel diplomacy and crisis-management mechanisms can help de-escalate tensions.
• Public Opinion: War-weariness in many countries may limit support for prolonged conflicts.

Recommendations for Risk Reduction:

• Strengthen Crisis-Management Mechanisms:

  • Reestablish military-to-military communications to reduce miscalculation risks.
  • Expand hotlines and deconfliction channels in high-risk theaters.

• Revive Arms-Control Diplomacy:

  • Negotiate a successor to New START to limit nuclear arsenals and enhance transparency.
  • Pursue confidence-building measures (e.g., limits on hypersonic weapons, AI in nuclear command).

• Avoid Provocative Actions:

  • Refrain from large-scale military exercises near disputed borders.
  • Limit rhetoric that lowers the threshold for nuclear use.

• Enhance Economic Resilience:

  • Diversify energy supplies to reduce vulnerability to disruptions.
  • Strengthen financial safeguards to mitigate the impact of sanctions and market shocks.

• Invest in Diplomacy:

  • Pursue diplomatic off-ramps in Ukraine, the Middle East, and the Indo-Pacific.
  • Support multilateral institutions to address global security challenges.
