The US does not recognize the demands made by a foreign country upon its citizens. If the person chooses to live as a US citizen, then no other country can force their citizenship upon him.
My sister was born in Germany of US parents. If Germany tried to enforce a claim of citizenship upon her, the US would tell them to take a hike.
And extending that, that no person born in the US, regardless of the citizenship of their parents, is amenable to citizenship claims by another country. So, a child born in the US, to German citizens, is a US citizen (natural born, to boot), and therefore has allegiance to the US. Must that person register for the US military draft, etc.?
Adding, that this quality pertains to naturalized citizens, just as much as it does to those who obtain citizenship other than by naturalization.

The modern day State Department rules discusses the problems associated with dual citizenship:
7 FAM 081: U.S. Policy on Dual Nationality:http://www.state.gov/documents/organization/86563.pdf(e)While recognizing the existence of dual nationality, the U.S. Government does not encourage it as a matter of policy because of the problems it may cause. Dual nationality may hamper efforts by the U.S. Government to provide diplomatic and consular protection to individuals overseas. When a U.S. citizen is in the other country of their dual nationality, that country has a predominant claim on the person.
...
the U.S. Supreme Court has stated that dual nationality is a "status long recognized in the law" and that "a person may have and exercise rights of nationality in two countries and be subject to the responsibilities of both." See Kawakita v. United States, 343 U.S. 717 (1952).
And of course, that's not even in the context of the NBC requirement for POTUS.
And not an NBC. And no, the US government won't do anything. The German government a few years a go sent my neighbor's son a letter in the United States saying he had to do compulsory German military service and he was born at Landstuhl, Germany at the US military hospital. He was born of two American citizen parents and the German government had a claim on him.
This is perhaps the most surprising argument birthers make--that one's U.S. citizenship is affected by a foreign country's laws. Not only that, but these foreign laws have an effect on the eligibility of our own President. This is not a conservative position. It's another example of how this hysteria is forcing conservatives to adopt some strange views and blindly follow dubious characters.
The US government recognizes duel citizenship and the possible claims by a foreign country may have on that person...because of the allegiance that person has to their respective foreign country which that person has citizenship.
Oops, you just stepped on your on d*ck
Bammies father was a British subject, the Brits by virtue of his birth right grants duel Citizenship whether bammie wants it or not...IOW half claim on him even if he was born here because of his Fathers Citizenship....just like your parents US Citizenship is claim over Germany.
