We need a standing army because in time of war we will be automatically prepared. The anti feds wanted a militia, but this was proved to be ineffective. A militia would not give us enough time or resources to prepare for the war that would come.
We, the federalists, want a big democracy. We believe that the uneducated majority can’t decide what to do in complex matters because they simply don’t have the ability to. The well-educated elites should have the responsibility of that job.
