In the cloistered corridors of Switzerland’s defence circles, a blunt admission this weekend by the outgoing head of the armed forces should have echoed far beyond the country’s mountains and lakes.

Lieutenant-General Thomas Süssli — a soldier accustomed to discretion — has publicly conceded what many have known for some time: Switzerland, the heart of Europe, is incapable of defending itself against a full-scale military attack. This declaration, delivered with measured gravity to the Neue Zürcher Zeitung, ought to jolt not just Bern’s political elite but the entire European security architecture.

For decades, Switzerland’s posture has been a curious blend of self-satisfied neutrality and budgetary thrift. This has been sustainable only so long as war itself seemed a quaint relic of history, confined to textbooks and, lately, the tragic fields of Ukraine. Yet General Süssli’s verdict is unequivocal: neutrality without capacity is a fantasy. It will not deter a determined adversary. Neutrality, he insists, has value only when backed by credible military strength.

This is a sobering moment of truth. A nation that prides itself on precision engineering, financial acumen and political stability is being forced to confront a strategic deficit of alarming proportions. Süssli revealed that in the event of a genuine confrontation, only one-third of Swiss soldiers would be fully equipped to respond. Cyber threats and attacks from non-state actors — hacktivists or terror cells — may be within reach, he argues, but anything resembling a concerted conventional assault is beyond the Swiss army’s current means.

To appreciate the scale of this failing, it helps to recall that Switzerland is surrounded by NATO states — France, Germany and Italy among them. These are countries with far greater military budgets and obligations under Article 5 of the North Atlantic Treaty. Yet, in an era defined by Russian revanchism and a resurgent China, the assumption that Swiss security will be inherited from its neighbours is naïve in the extreme.

The geopolitical fault lines that run through Europe have been starkly illustrated by Moscow’s war in Ukraine. That conflict was supposed to be a catalyst for change in European defence thinking, an object lesson that no country, however neutral, is immune from the tidal forces of great-power competition. But Süssli’s account suggests that Switzerland’s political classes have not internalised this lesson. Rather than respond to the new strategic environment with urgency, they have largely reiterated the old story: Switzerland is safe because it is neutral.

But neutrality in the 21st century is no talisman. History is replete with neutral nations that found their status irrelevant in the face of aggression. Belgium, the Netherlands and Norway — all neutral in the early days of the Second World War — discovered as much. Süssli’s reminder that “neutrality only has value if it can be defended with weapons” is not just doctrinaire; it is grounded in historical reality.

And yet, the government’s defence strategy remains sluggish. Switzerland currently dedicates about 0.7 per cent of GDP to defence, a figure that falls far below the already modest targets adopted by other European nations and a fraction of NATO’s informal 2 per cent benchmark. Bern has pledged to raise this to roughly 1 per cent by 2032, a timetable that will, in effect, leave Switzerland underprepared for decades. At that pace, full operational capability might not be achieved until 2050 — a horizon so distant that it might as well be a political abstraction.

There are practical problems too. Efforts to modernise artillery, renew ground systems, and replace ageing fighter jets with Lockheed Martin F-35A aircraft are underway but beset by cost overruns and political pushback. Critics question whether funds are being allocated wisely, especially in a federal budget already under strain. Yet curtailing defence investment on the grounds of fiscal prudence, when Europe’s strategic landscape is deteriorating, is a form of willful blindness.

This weekend’s revelations have already triggered debate in Swiss media and across social platforms. Commenters on Swiss forums have been quick to point out that public enthusiasm for defence spending is limited, in part because Switzerland has not fought a war in living memory. For many citizens, the idea of war is abstract, distant, and incompatible with the national self-image of peaceable mountain dwellers. Such attitudes — understandable in comfortable times — now verge on the irresponsible.

There are, of course, voices in Switzerland calling for reform. Some have suggested extending compulsory service to include civilian defence roles, or enhancing multinational training exercises to ensure Swiss troops are interoperable with allied forces. Others have argued for more revolutionary options, such as investing in asymmetrical deterrence or even reconsidering membership in collective defence structures.

Yet these ideas remain marginal in mainstream Swiss politics, where the twin myths of neutrality and exceptionalism have deep roots. What this crisis demands is not incremental tinkering but a fundamental reassessment of what Swiss neutrality means in the 21st century. Neutrality cannot be a footnote in defence planning; it must be the result of robust preparation, credible deterrence and clear strategic thinking.

Europe today faces an uncertain future. The conflicts in Ukraine, the rising assertiveness of Moscow, and the shifting dynamics of NATO all underscore an uncomfortable truth: peace is not a given, it is a policy choice backed by strength. Switzerland, with its tradition of citizen soldiers and national fortresses carved into the Alps, should be ideally positioned to defend its freedoms. But ideals alone cannot substitute for capability.

If Bern fails to act on these warnings with real urgency, this admirable country risks becoming a symbol not of impregnable neutrality but of strategic complacency. And that is a danger not just to Switzerland, but to the stability of Europe as a whole.
