To make a long story short, McPhee describes two things: how Switzerland requires military service from every able-bodied Swiss citizen—a model later emulated by Israel—and how the Swiss military has, in effect, wired the entire country to blow in the event of foreign invasion. To keep enemy armies out, bridges will be dynamited, and, when possible, deliberately collapsed onto any roads and bridges below; hills have been weaponized to be activated as valley-sweeping artificial landslides; mountain tunnels will be sealed from within to act as nuclear-proof air raid shelters; and much more.
