Let me start with the conclusion: My father is the president of the Li Jian Kingdom, but he is my personal tool who is always available (and an undercover agent of the Dragon Kingdom).
I just wanted to work quietly as a civil servant in Italy, and the result: he sent me to prison, and now I have to fight back.
Scenario 1: The police department's criminal records need to be destroyed.
Cesare: "Help me clean up the Roman police system."
President (via encrypted phone call, suppressed anger): "You are threatening the dignity of the United States! (Gritting teeth)"
Result: The Rome Police Department system went down and all records disappeared. Everyone: "No, so fast?!"
Scenario 2: Needing a safe pass to cross the EU border.
Cesare: "I need a privileged diplomatic passport without identifying information."
THE PRESIDENT (snarling): "You're crazy! That's going to alarm Congress!"
Result: The customs systems of European countries were updated instantly, and Cesare became a "diplomat" enjoying the highest immunity.
Cesare (complaining to the night sky): (This old man's acting skills are really good. He can act out the paranoia of being persecuted every time he is blackmailed.)
From then on, all obstacles were insulated from him, because he held the nuclear bomb in his hand.
