country, it ought certainly to be under the regulation and at the
disposal of that body which is constituted the guardian of the
national security. If standing armies are dangerous to liberty,
an efficacious power over the militia in the same body ought,
as far as possible, to take away the inducement and the pretext
to such unfriendly institutions. If the federal government can
command the aid of the militia in those emergencies which call
for the military arm in support of the civil magistrate, it can
the better dispense with the employment of a different kind of
force. If it cannot avail itself of the former, it will be obliged
to recur to the latter. To render an army unnecessary will be a
more certain method of preventing its existence than a thousand
prohibitions upon paper."
