BERN / ZURICH — Switzerland, long the standard-bearer for global neutrality, has issued its sharpest rebuke yet of the ongoing military operations in the Middle East. In a statement that has sent ripples through Western diplomatic circles, Swiss Defense Minister Martin Pfister declared that the U.S. and Israeli offensive against Iran constitutes a clear violation of international law and the prohibition of the use of force.

A Principled Stand on International Law

Speaking to the SonntagsZeitung, Pfister emphasized that while Iran’s retaliatory strikes are equally problematic, the initial U.S.-Israeli campaign has breached the UN Charter.

• Violation of Force: Pfister noted that the “The Americans and Israel have attacked Iran from the air. In doing so, they, like Iran, have violated international law,” calling for an immediate cessation of violence to protect the civilian population.
• Neutrality Trigger: Foreign Minister Ignazio Cassis added that the government is closely monitoring the “duration and intensity” of the conflict. If it persists, Switzerland may be legally bound to close its airspace to U.S. military aircraft and halt arms exports, similar to the measures taken during the 2003 Iraq War.

Domestic Security and Refugee Concerns

The Swiss government’s shift is largely driven by domestic security assessments. Pfister warned that Switzerland’s “perfected society” is no longer insulated from the fallout of Middle Eastern conflicts:

1. Asymmetric Warfare: The Defense Ministry has flagged a high risk of “terrorist attacks” in Switzerland as pro-Iranian actors seek soft targets in Europe.
2. Refugee Crisis: There are growing fears of a massive wave of refugees reaching the Alpine nation as Iranian infrastructure crumbles.
3. Defense Gaps: Pfister candidly admitted that Switzerland currently has “nothing to defend against long-range attacks”, emphasizing that the conflict should trigger a “long-overdue rethink” of national security.

Embassy Closure and “Good Offices”

In a sign of the deteriorating security environment, the Federal Department of Foreign Affairs (FDFA) confirmed on March 11 that it has temporarily closed the Swiss Embassy in Tehran. The Swiss Ambassador and five staff members have been evacuated by land.

Despite the closure, Switzerland continues to function as a “postman” between Washington and Tehran. Under its protecting power mandate, Swiss diplomats are maintaining an open line of communication to facilitate potential de-escalation talks, even as President Trump threatens “fire and fury” against the new Iranian leadership.
