Re: "all we would need to do is leave people alone"
Love that video Vincent...and to speak a little further on the matter of their national security - not only do they require military training and keeping civilians armed, they also have shelters built into the mountains with years and years of supplies ready to go (all provided by the government). Their highway medians are removable and their highways become emergency airstrips. It is also mandatory that all houses and apartment buildings have fallout shelters built on the property. Many of their bridges, roads, tunnels and railways are wired with explosives as well, but this is an old practice from WWII and the Cold War days (though IMO I see no reason to stop doing it).
They are a country that hasn't seen or been in war for over 100 years, yet they have the capacity to have a large, capable army ready in a very short amount of time. They are also very economically stable. Their country is like a blueprint for domestic success and stability.
