Does Reza Pahlavi want to be the Shah?

Reza Pahlavi, son of Mohammad Reza Pahlavi has spoken frequently about how he wants the Iranian regime to change. However, he is quite ambiguous with what he means when regarding what the form of government for Iran should be. Repeatedly he has expressed his desire for Iran to be a secular democracy. Is he simply biding his time trying to draw support by appearing to be "liberal" and "secular"? Does he not believe he is fit for the role? (Perhaps PTSD after his father being overthrown or something similar). Or does he truly believe Iran should be a secular democracy?
