The fancy word for it is revanchism.
People who study words and language call it a borrowed word, meaning that we use it in English but got it from the French word. In this case, it is the French word for revenge.
People familiar with history are most likely to associate the word revanchism with the struggle between France and Germany that lasted from 1870 until 1945. The Prussians defeated the French in 1870 and took two territories – Alsace and Lorraine – that many in France wanted back.
Desire for revenge for regain of the lost territories was an important aspect of French policy against Germany at Versailles in 1919. The tension between the two countries lasted until, after another world war, Germany was simply destroyed as a single country and France got the territories back.
