IPB Condemns U.S. Strikes on Iranian Nuclear Sites: An Illegal Escalation

Berlin, June 22, 2025

The International Peace Bureau (IPB) strongly condemns the United States’ recent military strikes on Iranian nuclear facilities at Fordow, Natanz, and Isfahan. Carried out in coordination with Israel, these attacks are a dangerous escalation that violates both international law and the U.S. Constitution—and brings the region closer to a devastating war.

Under international humanitarian law, nuclear facilities are protected due to the catastrophic risks they pose to civilians and the environment. Targeting them is inhuman and illegal. There is no credible evidence that Iran is currently pursuing nuclear weapons—U.S. intelligence has confirmed this repeatedly. Military action under these circumstances has no legal justification.

Domestically, the strikes also violate the U.S. Constitution, which grants Congress—not the President—the authority to declare war. Launching attacks without Congressional approval contradicts both the War Powers Resolution and the principles of democratic oversight.

This is more than a legal issue—it is a matter of global security. Attacking nuclear infrastructure risks the release of radioactive materials, retaliatory strikes, and rapid regional escalation. The consequences could be catastrophic—not just for Iran and the Middle East, but for the world. The USA and Iran should cease hostilities and return to serious, long-term negotiations.

NATO members must not follow a U.S. president who acts unlawfully, even within his own constitutional system. They have a responsibility to uphold international law and prevent escalation—not enable it. Silence or complicity only deepens the crisis.

There is no military solution to this crisis. IPB calls for an immediate end to all military operations, respect for international law, and return to diplomacy. Peace and common security can only be achieved through cooperation, not weapons.

Statement:  Call for De-escalation in the India-Pakistan Military Standoff

9 May 2025

The International Peace Bureau (IPB) condemns the heinous attack in Pahalgam -Kashmir on 22 April, where 26 civilians lost their lives, as well as the retaliatory attacks which have killed civilians on both sides of the line of control and in Pakistan’s sovereign territory. IPB condoles with the victims’ families and friends. Terrorism of any kind from any source is unacceptable to civilized society and the international community condemns such acts.

IPB understands that at times of national grief there is a call for retribution. However, we believe that military standoffs escalate an already tense situation and can spiral into full scale wars with disastrous consequences for countries and peoples. These military conflicts destabilize entire regions, disturb the economy, and immiserate people. Once initiated armed conflicts can go on for a long time. Any confrontation between two nuclear-armed powers like India and Pakistan is a threat to the world – as outlined in publications like the 2019 Bulletin of Atomic Scientists’ How an India-Pakistan nuclear war could start – and have global consequences – and both these countries must heed the calls of the international community and cease military confrontations that can lead to a nuclear exchange.

The IPB appeals to both the governments of India and Pakistan to immediately halt all military confrontations, cease the spiral of retributions and return to calm. All indirectly involved states – including the United States, Russia, and China – must likewise call for de-escalation and diplomacy and reject provoking the conflict for their own interests where all are major arms suppliers. There is no substitute for bilateral and regional diplomacy, dialogue, and engagement. World history has repeatedly shown that common security is the most rational and sustainable way to both peace and development.

The IPB hopes that both the Governments of India and Pakistan resort to reason and de-escalate these tensions with immediacy.

Presidential candidates must present plans for building peace through dialogue and trust, not military expansion

  1. Yoon Suk-yeol has been impeached. Throughout his term, Yoon — who advocated for “peace through strength” and designated Democratic People’s Republic of Korea as the “main enemy” — exploited the division system and heightened tensions on the Korean Peninsula for political gain, even at the risk of a localized conflict. Despite insufficient tax revenues, he increased defense spending and fixated on an endless cycle of confrontation. Meanwhile, peace vanished entirely, and the two Koreas spiraled into repeated cycles of hostility and standoffs. All dialogue channels were severed, and even the September 19 Military Agreement-which served as a safety pin to prevent armed clashes-was scrapped. Repeated psychological warfare and military drills near the border have severely endangered the peaceful survival rights of residents in those areas. Yoon Suk-yeol’s “peace through strength” policy has utterly failed.
