No, an American Citizen can be a Dual-Citizen of many countries. There are some countries which don't allow that. In some countries it is dangerous to be a dual-citizen since if the dual-citizen is inside the country he can be drafted for military service (Greece, for instance).
Japan requires a renunciation of citizenship to all other homelands, for example. Reason being, if you are a Japanese citizen, you are Japanese.
I'm not clear on how the U.S. handles the situation though. I've never really sat down and researched what happens if you renounce citizenship to a country that states that by blood we are citizens.
It depends on the laws of the other country. US allows two citizenships, so if you have one other you can aquire the US one as well. If you are a US citizen and you move to another country, it is up to their laws about whether you can keep your citizenship if you want to take theirs.
