They came, they saw, they re-conquered

A Washington Post article about Russia's incursion into the former Soviet republic of Georgia brings in another word I had to look up:

"There is a Russia narrative that 'we were weak in the '90s, but now we are back and we are not going to take it anymore.' But being angry and seeking revanchist victory is not the sign of a strong nation. It is the sign of a weak one," said Daniel Fried, assistant secretary of state for European and Eurasian affairs.

That comes from revanche, a French word which Merriam-Webster online defines as "revenge, especially a usually political policy designed to recover lost territory or status."
