EU already absorbed Switzerland in this pic despite them not wanting it, so there’s that.
They are completely landlocked by the EU and their Airspace.
Also most of their imports/exports go there.
They don’t even farm enough to sustain themselves. So yes, obviously it’s true
I mean they mostly are, they’re approx. 50% dependent for agriculture, so if the EU were to block all borders and halt all exports to them the Swiss would become significantly skinnier than they were before.
No shame in that by the way, the Swiss also provide the EU with lots of stuff and services that are valuable.
