[The First Avenger] Where did Hydra get all of its soldiers ?

This movie takes place during WW2 so most men where fighting for the Allies or Axis powers so that alone would make recruitment difficult. And judging from the looks of each base or factory, Hydra had hundreds of people operating at those places. How did Red Skull get all of these people devoted to his cause ?

Hydra is theoretically part of the axis war machine - most were probably bog standard soldiers (maybe SS units) assigned to a weapons development team that promised Hitler they could single handedly win the war (and *would* have had Cap not shown up). Once there, they were probably “radicalized” into believing Red Skull was a better leader than Hitler for the new world order.
