Swiss Army Chief Warns Country Cannot Withstand Full Scale Attack

Lieutenant General Thomas Suessli, commander of the Swiss Armed Forces who is stepping down at the end of the year, told the NZZ newspaper and Reuters in an interview published Dec. 27 in Zurich that Switzerland “cannot defend itself against a full scale attack” and must raise military spending to close urgent capability shortfalls. His blunt assessment framed a debate that reaches into public finances, procurement plans and the country’s posture of armed neutrality.

Suessli said the army is prepared for attacks by nonstate actors on critical infrastructure and for cyber incidents, but faces “major equipment gaps” against conventional, long range threats. “What we cannot do is defend against threats from a distance or even a full scale attack on our country,” he said, warning that in a real emergency only about one third of Swiss soldiers would be fully equipped. He invoked the Russian invasion of Ukraine as a turning point that required “ruthless honesty” about readiness, and added that he did not sense a national jolt in public attitudes since then.

The arithmetic of the shortfall is stark. Switzerland currently spends roughly 0.7 percent of gross domestic product on defence and has set plans to lift that to about 1 percent by 2032. Military planners and outside analysts cited in recent coverage estimate that at current trajectories core readiness for conventional war would not be achieved until around 2050, a timeline Suessli described as unacceptable given rising geopolitical risks in Europe. Planned procurements include artillery modernisation and the purchase of F 35A fighter jets, but fiscal and political constraints threaten delivery schedules and operational integration.

Budget politics are central. A 2020 referendum limits breaching Switzerland’s budget ceiling and Finance Minister Pfister has framed spending limits as fiscal discipline while emphasising that robust air defence remains non negotiable. Pfister has said that 36 jets are the bare minimum for air defence. The clash is typical of advanced economies where defenders of fiscal conservatism warn of crowding out social spending while security advocates point to the asymmetric and irreversible costs of being under armed.

Suessli also pressed the case for interoperability with partner militaries, arguing that neutrality only has value “if it can be defended with weapons.” He warned that Switzerland cannot expect to shield itself autonomously and stressed that years of preparation are required to be able to operate together with other armies. Alongside conventional gaps, he has been a vocal proponent of strengthening cyber defences and countering hybrid threats such as disinformation and attacks on telecoms.

Market and industrial implications are emerging. Large U.S. defence technology companies are increasingly courting Switzerland as the country modernises, a shift that could spur defence procurement spending, domestic supplier contracts and technology transfers. For policymakers the choice becomes a question of timing and priorities, whether to accelerate spending to close immediate risks or to maintain slow glide paths that preserve fiscal rules.

Suessli framed his appeal as a simple warning to politicians and the public, that they “must not believe that the army is capable of defence when it is not.” The statement leaves Switzerland at a crossroads between sustaining a long standing model of armed neutrality and adapting to a security environment that demands faster investment and deeper international ties.
