But is that any worse than defaulting to the side with less power? At the end of the day if you have to side with one or the other, whoever happens to have power at the time seems like pretty arbitrary criteria. If instead Israel were the lesser power being bullied by a powerful Palestine, would you side with Israel? How about if Nazi Germany were getting bullied by Western powers, would you side with them? It wouldn't make sense because Nazis are very obviously the bad guys. Anyway it's not just about power.
