While being recruited, a spy will be promised lots of things, including money, sex, and a safe retirement. Since there’s a threat their betrayal may someday be exposed, retiring in their own country would be far too dangerous. Many hope to be sent to America, hence Lady Liberty in the background. America is the biggest carrot to dangle in front of potential spies, but in reality most will be placed in Europe or Scandinavia. It is rare for agents to end up in the United States.
