Really, most Americans just aren't that into politics (or war), and more power to them.
Farmers aren't that much more into having bloody battles on their land than city folks are.
And this is what the Founders intended -- if by the Founders, you mean the people who wrote the Constitution and put it into effect, rather than those who got the Revolution started.
Really? War WILL come to them eventually, making demands that impact their lives. It's the nature of the beast.
