Explain the Tokyo Convention's jurisdictional system and the 2014 Protocol's modernisation.

The unlawful seizure (the "hijacking") = the aircraft's control-taking by force-or-threat aboard (the Hague Convention's definition-family: the violence, the intimidation, the device's use against the person-and-crew). "Aerial piracy" — the rhetorical label's caution: the piracy-of-the-sea analogy (the universal jurisdiction's temptation) against the treaty-law's careful system (the jurisdiction's allocation, not the universality) — the exam's precise line: the hijacker is the treaty- offender, not the pirate-of-law.
