Unfortunately, as an Israeli, you were indoctrinated in both school and most likely, the IDF. The ethnic of cleansing of the Palestinians was already 50%. completed by the time any outside Arab forces arrived on the scene. The seven armies you speak of never numbered as many as the zionists/Israelis were able to put in the field. The only one that the zionists (who were British trained via the armed police forces) had reason to fear was the Jordanian Arab Legion (also British trained) hence the agreement to give control over what came to be called the West Bank to Jordan.
