Ukraine will continue to fight for what is rightfully theirs
Out of curiosity, how do you define rightfully in that case?
If that “rightfully” is defined as “they owned it before”, how long ago does it go? 5 years? 10 years? 100 years? Or just for as long as it is convenient for you? Should Mongolia try to reconquer all the territories it once owned?
Or is it “rightfully” as in “recognized in international law”/“defined by UN” or something like that? In that case, you surely agree that China should fight for Taiwan, right?
