Summary: The European security architecture has fundamentally changed since 2022. Finland and Sweden joined NATO, the EU is massively expanding its Common Security and Defence Policy (CSDP), and the USA under President Trump demand more European self-reliance. Switzerland is the only European state that is neither a NATO nor an EU member and simultaneously remains neutral.
On 4 April 2023, Finland joined NATO as its 31st member. Finland had pursued a policy of military non-alignment since the Second World War. The Russian attack on Ukraine led to a rapid shift in opinion: NATO support rose from 25% to over 75% within a few weeks [1].
On 7 March 2024, Sweden joined NATO as its 32nd member. Sweden too thus abandoned a tradition of non-alignment spanning over 200 years [1].
NATO enlargement has drastically reduced the number of neutral/non-aligned states in Europe and increased pressure on the remaining neutral states.
| State | Status | EU member | NATO member | Particularity |
|---|---|---|---|---|
| Austria | Constitutionally neutral | Yes | No | Participates in EU CSDP |
| Ireland | Militarily non-aligned | Yes | No | "Triple Lock" for military deployments |
| Malta | Constitutionally neutral | Yes | No | Smallest EU state |
| Switzerland | Permanently neutral | No | No | Only state neither EU nor NATO |
Switzerland occupies a unique position: it is the only European state that is simultaneously neutral AND belongs to neither the EU nor NATO [2].
The EU's Common Security and Defence Policy (CSDP) has been massively expanded since 2022 [3]:
For Switzerland as a non-EU member, CSDP is not directly relevant, but the EU-wide rearmament trend indirectly generates pressure on Swiss defence policy [3][4].
The neutrality debate takes place against the backdrop of an increasingly fragmented world order:
Switzerland faces threefold pressure [5]:
The ETH study "Security 2025" shows that over 80% of the Swiss population perceive high value congruence with Northern, Western and Central Europe -- but only a minority supports NATO membership (32%) [6].
The initiative seeks to set clear boundaries in this context: constitutional prohibition of military alliances and economic sanctions. Supporters see this as protection against creeping rapprochement; opponents see it as dangerous self-isolation.
