Depending on the definition of the word "nation" there are two very different answers.
Nation as a Politically Sovereign Entity: Israel was created entirely on land that constituted part of the British Mandate of Palestine. A mandate is a sub-national, colonial entity and is certainly not a nation. Therefore Israel did not "replace" or "displace" any nation if this sense of the term is understood. (Would someone say that the creation of the United States displaced a politically sovereign nation? - same argument)
Nation as a metaphor for a Conscious Ethnic Group:Whether the Israelis intended to or not (there is much debate on the subject), Arab Palestinians who lived in the British Mandate of Palestine were forced to flee in some parts and were scared into fleeing in other parts of the territory that would become Israel. The Palestinian People were certainly displaced by the Creation of the State of Israel and the ensuing war that this action provoked.
