And the relevance to the US Constitution is ... ?...R
I think Hitler is quite relevant. After WWI Germany was a democracy and there were lots of weapons kicking about. Hitler managed to get control of an organised, uniformed, armed, militia the "Brownshirts" and he attempted to gain control of the country in a putsch. He failed and ended up in jail.
He then made a comeback but instead of attempting a revolution from below he took control of the levers of power from above. Once he had control of the army the country was his.
I think the American founding fathers favoured a country with lots of citizens militias that would unify in times of national threat rather than a large standing army. Somebody unsavory might take control of a militia but they could not take over the country (just as Hitler failed), but if somebody took over a standing army the country was theirs (again just like Hitler).
Now there is the example in the US of one man, who many regard as unstable, having an enormous amount of power, largely unchecked, in his hands.
