When the constitution was being drafted over 220 years ago, the new political entity was a vastly different place in many ways: smaller population, largely rural, communities somewhat dispersed and isolated, and alert to the need to defend their revolutionary freedoms and ideas, compared to the present highly integrated, educated, regulated, complicated union.
It is hard to see the need for “militia” nowadays given the multiplicity of armed agencies to protect the country and people, such as the army, navy and air force, police force, state troopers, coast guard, FBI/CIA, etc, and more importantly, free speech, a free press, the courts and democratic elections.
