And British actions were motivated by claims of jurisdiction, calenel.
You are also ignoring the entirety of the body of law pertaining to jurisdiction. Jurisdiction applies to everybody except the specific classes of people that are exempted by treaty or other very limited and special circumstances. Diplomats are exempted by treaty. Before 1924 Indians (subject to tribal law), children of hostile occupying forces (by definition, occupied territory is not under the jurisdiction of the pre-occupation government) and persons transient through US airspace or waters (by far the weakest definition) are all exempted.
And I'm still waiting on that other definition.
