hey i got you a good one. lebanese civil war. lebanon used to be majority christian and they still allied with palastine and even after jordan kicked them out after trying to take over the country the lebanese took them in and what did they do in return? support hezbollah and slaughtered the very christians that supported them and took them in. this wasn't thousand years ago or even a hundred years ago, it as during the 80s and lasted till the 2000s.
