The history of sovereign nations is the history of ‘consequences or not’, as compared to ‘right or wrong’ - for a great many reasons, including that right or wrong is generally a cultural idea that is rarely consistent across cultures, and is often fluid based on trade offs and not as set in stone as we’d all like to believe.

If folks were foolish enough to assume a sovereign nation was going to do what they think is right or wrong (including following a treaty when there are obviously no real consequences despite it benefiting them to not follow it), then they weren’t paying attention to history.
