It is more a subject of joy that we have so few of the desperate characters which compose modern regular armies. But it proves more forcibly the necessity of obliging every citizen to be a soldier; this was the case with the Greeks and the Romans, and must be that of every free State. Where this is no oppression, there will be no pauper hirelings. We must train and classify the whole of our male citizens, an make military instruction a regular part of collegiate education. We can never be safe till this is done.
-- President Thomas Jefferson
Short of a revolution I simply don't see this happening.
