In the sense in which both Trumbull and Howard used the phrase, they ARE subject to the complete jurisdiction of the United States.
The phrase was used in regard to INDIANS. There was a good deal of discussion about INDIANS IN TRIBES. These were considered subject to the PARTIAL jurisdiction of the United States, because they lived on United States land.
Aliens "in amity" were always considered subject to the COMPLETE jurisdiction of the United States. Nobody ever said differently. If you maintain that's the case, then produce the quote that says aliens here in amity were not subject to the complete jurisdiction of the United States. NOT from someone who thought otherwise LATER, but from the Senators and Representatives who introduced the 14th Amendment.
YOU CAN'T, BECAUSE THAT QUOTE DOESN'T EXIST.
You simply don't have a clue what you're talking about.
Indeed, they DID say differently, Jeff. U.S. Secretaries of State said differently and so did an International Arbitrator.
