That is a false analogy. Israel and Ireland have an extended invitation to grant citizenship to anyone of that nation's bloodline, but that is a very different thing from compelling you to serve that nation.
In the various wars fought between the French and the British, men have been EXECUTED for Treason because they were captured by a side that claimed their allegiance.
Italy also has a long standing policy of granting citizenship to the children of Italian descent. During World War II Italy and the United States were on opposite sides. Had someone been born in Italy to an Italian father and an American mother (Aldo Mario Bellei comes to mind) he would have been COMPELLED to fight in the Italian army against the United States.
Had he claimed to be an American, and was therefore exempt, they would have thrown him in the army or they would have thrown him in prison.
There are real world consequences to getting moral and principled clarity on this issue. The Notion that someone who could have been compelled to fight in a Foreign Army against us is qualified to be our President is nonsensical and ridiculous.
The Current Administration ought to make it obvious why it is a disaster to allow a non natural citizen to get control of our country. He has no loyalty to us, nor our principles, and he shows us this every day.
You are using a two-century-old example of rule by the whims of monarchs (one constitutional, the other absolute) as precedent for American constitutional law. Do I need to point out the problems with that?

"Dual citizenship," as a legal status, does not exist in most of the world, except in countries where it's prohibited. If you are a citizen of Italy and the United States, under Italian law you are an Italian. Under US law you are an American. Not partly, not sorta kinda. You are required to use your US passport when entering or exiting the US; what happens at any other border or in any other country is not under US jurisdiction.
The Notion that someone who could have been compelled to fight in a Foreign Army against us is qualified to be our President is nonsensical and ridiculous.
The notion that a foreign country's laws can be allowed to dictate who is and who is not eligible to be president of the United States is nonsensical and ridiculous. Suppose Saddam Hussein, in 2000, had declared George W. Bush to be a citizen of Iraq. Would that have made him ineligible to be president?
