If you have 26 minutes and want to become more wholistic about the conflict, watch the Israeli narrative that beats the Arab narrative by a mile. There are a few things that should be added here.
The British switched sides from Jewish to Arab after 1939 for fear that the Arabs (much bigger population than Jews) would join the Nazi camp. The British were also disappointed that the French conceded to Nazis and London believed that it should take the whole Mideast to itself. When the French came back in 1945, they took Israel's side while Britain was on the Arab side until 1956, when Nasser's nationalization of Suez brought them back together against him. To understand how the British took the Arab side against Israel, think who took the West Bank and East Jerusalem from Israel. It was the Jordanian Army led by British general Glubb Pasha.
My professor at AUB left Haifa while a kid with his family in 1948 to Alexandria. He used to tell us in class that they left everything in their house as is thinking they would come back from a summer vacation in Alexandria. They were told that the Iraqi Army was coming, would destroy Israel, then they could come back. The Arab armies did come, but they only took the West Bank that Jordanian King Abdullah I wanted to annex. His rivals, at the time the Saudis, vetoed the move at the Arab League, and that's why the West Bank stayed in limbo, a former mandate land without any recognized sovereignty over it (until today). In 1964, Nasser was engaged in war against Saudi and Jordan, in Yemen, and wanted to undermine Saudis and Jordanians, so he instigated the Arabs of the West Bank to secede by proclaiming Palestine in the West Bank and Gaza (then join him in union after Syria had exited the United Arab Republic in 1961). The Palestinians gathered in East Jerusalem and planned to proclaim their state in the West Bank and Gaza, but the Saudis shot down the creation of Palestine at the Arab League because they didn't want to allow their rival Nasser an easy win. Instead, the Saudis propped up their own Palestinian faction that doubled down by saying Palestine would not be West Bank and Gaza only, but all of Mandate Palestine. This was Yasser Arafat. After losing in 1967 and 1973, Saudi and Egypt came to the conclusion that the eradication of Israel was impossible, and decided to share the land with Israel and create Palestine on West Bank and Gaza only, but now it was the radical crazies (Iraq, Syria, Libya) who shot down such plan and propped up Palestinian radical militias. When these Arab regimes weakened, Iran picked up the tab in 1979, has been doing so since. The rest is history.
