Turmoil in Global Nuclear Landscape: Rising Tensions and Renewed Nuclear Anxiety

The global nuclear landscape is once again in turmoil, as rising geopolitical tensions, renewed military rivalries, and political unpredictability challenge decades of efforts toward disarmament.

From U.S. President Donald Trump’s claim that Pakistan has resumed nuclear testing, to Russia’s modernization of tactical weapons, and North Korea’s renewed provocations, the world appears to be entering a new phase of nuclear uncertainty.

Experts warn that this escalating environment could destabilize fragile regions, undermine global non-proliferation treaties, and trigger a new arms race reminiscent of the Cold War — but far more complex and multipolar.

Recent Trigger: Trump’s Pakistan Claim and Regional Fallout

In an interview on CBS News’ 60 Minutes, President Trump alleged that Pakistan, Russia, China, and North Korea are all engaged in nuclear weapons testing.
Although no independent verification or seismic data supports these claims, the remarks have created shockwaves across diplomatic and security circles.

Pakistan — battling an economic crisis, insurgent violence, and political instability — has not conducted any confirmed nuclear test since 1998. Yet, the suggestion alone has reignited fears of South Asian instability and renewed nuclear posturing.

Analysts warn that even unverified statements can erode trust, especially in regions like South Asia, where nuclear-armed rivals India and Pakistan remain locked in long-standing security competition.

The New Nuclear Reality: A Fractured Deterrence Order

The post-Cold War order that restrained nuclear ambitions is visibly fraying.
Where once arms control treaties and global monitoring systems provided stability, the 2020s have seen diplomatic paralysis and rising distrust among major powers.

Key Trends Fueling Global Nuclear Turmoil

1. Breakdown of Arms Control:
   The INF Treaty between the U.S. and Russia collapsed in 2019. The New START Treaty faces uncertainty post-2026, with both sides accusing each other of violations.

2. China’s Rapid Expansion:
   Beijing is reportedly building new missile silos and expanding its nuclear arsenal beyond 500 warheads, challenging U.S.-Russia parity.

3. Russia’s Tactical Threats:
   Moscow’s war in Ukraine has revived fears of battlefield nuclear use, especially with deployments near Europe.

4. North Korea’s Defiance:
   Pyongyang continues to conduct missile launches, threaten Japan and South Korea, and develop miniaturized warheads despite UN sanctions.

5. Iran’s Uncertain Path:
   The JCPOA (Iran Nuclear Deal) remains defunct, with Tehran enriching uranium beyond 60%, close to weapons-grade levels.

6. Pakistan’s Internal Fragility:
   Trump’s remarks have placed global focus back on Islamabad’s nuclear security amid economic collapse and militant resurgence.

Erosion of Non-Proliferation Regimes

The Comprehensive Nuclear-Test-Ban Treaty (CTBT), though widely supported, still hasn’t entered into force because key states — including the U.S., China, Pakistan, and North Korea — have not ratified it.
Meanwhile, the Nuclear Non-Proliferation Treaty (NPT) is struggling to stay relevant as modernization, miniaturization, and tactical nuclear programs blur traditional definitions of deterrence.

Result:

• Increased risk of miscalculation

• Diminished trust in verification systems

• Growing nuclear competition among regional powers

Strategic Flashpoints in 2025

Russia–Ukraine War and Tactical Nuclear Risks

Moscow’s nuclear rhetoric has become more aggressive since 2022. Western intelligence suggests Russia has repositioned non-strategic nuclear weapons in Belarus, raising fears of escalation.

China’s Expansion in Indo-Pacific

China’s military buildup in the South China Sea and its hypersonic glide vehicle tests have alarmed the U.S. and its allies.
Beijing’s refusal to join trilateral arms control talks further complicates efforts to maintain stability.

North Korea’s Provocations

North Korea continues to defy international sanctions, boasting of new solid-fuel ICBMs capable of reaching the U.S. mainland. Analysts fear it could conduct its seventh nuclear test at any time.

South Asian Uncertainty

India maintains a “no first use” nuclear doctrine, but Pakistan’s tactical nuclear posture and Trump’s unverified remarks risk reviving mistrust and military brinkmanship across the subcontinent.

Expert Opinions

• Dr. Vipin Narang, MIT Security Studies:
  “The erosion of arms control agreements and inflammatory rhetoric from global leaders are undoing 50 years of progress in nuclear restraint.”

• Heather Williams, King’s College London:
  “We are witnessing a multipolar nuclear world — with more actors, fewer rules, and higher risks.”

• C. Raja Mohan, Indian Strategist:
  “South Asia cannot remain insulated from global nuclear trends. The U.S.–China rivalry and Pakistan’s instability amplify regional dangers.”

The Role of Technology in Modern Nuclear Strategy

Advancements in AI, hypersonic missiles, and satellite surveillance are transforming deterrence and decision-making:

• AI-driven defense systems shorten reaction times, increasing risk of accidental escalation.

• Hypersonic weapons blur the line between conventional and nuclear delivery systems.

• Cyber threats to nuclear command networks create new vulnerabilities for every major power.

The Road Ahead: Need for Renewed Dialogue

As global instability deepens, the need for new arms control mechanisms and confidence-building measures is urgent.
Diplomatic initiatives like:

• A “New START 2.0” framework involving the U.S., Russia, and China

• Regional Non-Proliferation Pacts in South Asia and the Middle East

• Enhanced IAEA inspections and transparency commitments

… could help rebuild trust and prevent a spiral of nuclear escalation.

India’s Strategic Position

India continues to maintain its credible minimum deterrence and no-first-use policy, focusing on modernization and command reliability.
Given the shifting global nuclear order, India’s stance emphasizes strategic stability, responsible deterrence, and support for global disarmament frameworks.

Conclusion

The global nuclear landscape in 2025 stands at a precarious crossroads.
Trump’s remarks about Pakistan’s alleged nuclear testing may or may not hold factual weight, but they reflect a deeper truth — the world is drifting back toward nuclear brinkmanship.

In an era of fractured alliances, weakened treaties, and emerging technologies, global powers must urgently return to the table to prevent the next crisis from being not just political — but existential.
