One way is to make it damn expensive for anyone who might want invade, protecting the civil population even as it joins in the job of defending the country, and blocking entry points to the extent that the country can "button up" and remove itself from the outside world.
And this is what the Swiss did--and still do. Those beautiful mountains? Honeycombed with military installations. The scenic bridges? The tunnels? Mined and ready to collapse. The pretty little houses overlooking the roads? False fronts for artillery. The rifle hanging over the fireplace? That's not for show--everyone has military training.
The Swiss have natural advantages. But that is not enough. They also have the will and the tradition of making the most of what they have.
There's a story--perhaps apocriphal--that a Nazi official threatened a Swiss diplomat with invasion. "We outnumber you," he said. "Even after your defenses, if we invade we'll outnumber you two to one."
The diplomat replied, "In that case, each of us will shoot twice."
And that is how you maintain your neutrality.
