I'm not asserting anything. I'm asking questions.
Mexico intervenes on behalf of it’s citizens because Mexico has jurisdiction.
Really? Mexico can petition the US Government to treat its citizens in a particular way, just as the US Government can petition foreign governments to treat US Citizens in a particular way. Ask Britney Griner how that works ... She's free ONLY because we had something the Russians wanted, and they were willing to trade. When you go to a foreign country, you're subject to ITS laws; IT will punish you if you break them.
What does jurisdiction mean? What jurisdiction does Mexico have in USA? What jurisdiction does USA have in Mexico? How is someone physically present in the USA NOT subject to the jurisdiction thereof?
I did not mean that the way you took it. It was a version of saying the situation is not that simple. The question is what does jurisdition mean. If you visit France you must obey it’s laws and are under it’s immediate Jurisdiction. If there is trouble the US consulate will help because you are a US citizen under the jurisdiction of the US. There are varying levels of jurisdiction. A child born to foreign citizens on US soil is a citizen of the parents country(ies) at birth. The US grants citizenship by statute to these same children who are dual citizens at that point.
