Iran's nuclear ambitions echo Ukraine's fateful disarmament

Global Watch | 2026-03-23

Europe and the world stand at a crossroads where unchecked nuclear programs by aggressive regimes could reshape global security forever.

Iran's relentless push for atomic capability threatens not just Israel but the broader international order through blackmail, proxy wars and regional chaos — including potential energy shocks, terrorism sponsorship, and migration crises for Europe.

The hard-won lesson—one painfully illustrated by Russia's invasion of Ukraine— is clear: nations that pose existential threats to their neighbors must never acquire these weapons of mass destruction.

Iran's existential threat

For decades, Iran's regime has openly called for the destruction of Israel while building a network of proxies and missiles aimed at the Jewish state and its allies.

Israeli Prime Minister Benjamin Netanyahu captured the urgency perfectly when he declared that the world "must at all costs prevent Iran from obtaining nuclear weapons."

Without decisive action to dismantle enrichment facilities and ballistic-missile programs, Tehran could gain the ultimate shield behind which it could escalate attacks with impunity.

Analysts warn that Iran's expanding centrifuge capabilities and enriched uranium stocks bring it closer to weapons-grade material, heightening the risks of nuclear blackmail against Europe alongside regional chaos.

Analysts at the International Institute for Strategic Studies and CSIS have long warned that a nuclear Iran would trigger a cascade of proliferation across the Middle East, embolden terrorism and expose Europe to energy shocks and migration crises.

The regime's record—sponsoring attacks from Gaza to Lebanon and beyond— leaves no doubt: this was not a peaceful energy program but a direct threat to global stability.

Stopping it is not optional; it is a necessary defense of the rules-based order.

Ukraine's disarmament lesson

Contrast this with Ukraine's experience.

In 1994, Kyiv surrendered the world's third-largest nuclear arsenal under the Budapest Memorandum, trusting security guarantees from Russia, the United States and Britain.

Ukrainian President Volodymyr Zelenskyy later called the decision "absolutely stupid, illogical, and very irresponsible."

Had those weapons remained, most analysts agree Russia would never have launched its full-scale invasion in 2022.

Instead, a conventionally armed Ukraine faced a nuclear-armed aggressor that used its arsenal as a shield, advancing conventionally while deterring NATO.

Today, Russia shows the danger of such power in threatening hands.

President Vladimir Putin has warned that deeper Western involvement in Ukraine "threatens a conflict with the use of nuclear weapons and the destruction of civilization."

His doctrine lowers the threshold for their use, modernizes delivery systems and pairs them with hybrid warfare.

Nuclear weapons are meant to deter, not to facilitate conquest. When held by nations committed to international law, they can help preserve peace.

But in the hands of expansionist regimes such as Iran and Russia, they become tools of coercion, blackmail and domination.

The Ukraine precedent proves the point: a disarmed Ukraine invited aggression; a nuclear Iran would have posed the same danger on a far larger scale.

Analysts stress that proliferation by hostile states erodes the non-proliferation regime and invites copycat programs.

The message is clear: preventing Iran from crossing the nuclear threshold was vital not just for Israel's protection, but for upholding the principle that such weapons must never fall into the hands of states seeking conquest.

As Russia brandishes its arsenal over Ukraine, global security depends on enforcing that red line today and in the future.
