From the article you cite:
“Yoma Ben-Sasson, Haganah commander in Givat Shaul, said after the village had been captured that, “there was not even one incident between Deir Yassin and the Jews.”[22] The view was echoed in a secret Haganah report which stated that the village had stayed “faithful allies of the western [Jerusalem] sector.”[2]”
Deir Yassin had ordered three groups of Arab militants to move off, and they did.
Irgun and Lehi were a nasty lot. Not all the Israelis went so low, but neither did Israel investigate or punish or disavow their terrorists to any degree.
Yoma Ben-Sasson was happy to lie to attack the Revisionist Zionists, even if it meant that all Jews and Israel would have their reputation harmed. Labor/Socialist Zionist scum have a long tradition of such lies. It is how they gained power int he 1930s, collaborated with the British to keep religious and revisionist Zionist Jews from immigrating, and set up the institutions in Israel. And this included violence, like Rabin firing arterllery ont he Altalena, an Irgun ship carrying refugees and weapons.
