The This study aimed to investigate the repercussions of the 1967 Arab-Israeli war and its repercussions on the Palestinian national project, in light of the variation in Palestinian and Arab visions of the means of liberation. The main problem of the study is the divergent views on the Palestinian National Project, where people were divided between the vision of comprehensive national liberation for Greater Palestine from the sea to the river, and the vision of partial and possibly interim national liberation for small Palestine (West Bank and Gaza Strip). The researcher used the analytical historical approach through tracking the events of the 1967 war, studying the available documents, in addition to the documents of the Palestinian national project, what historians and experts wrote, and interviewing the leaders of the Palestinian factions and Palestinian political analysts to reach the facts about the implications of the setback to the Palestinian National Project and trying to analyze it to reach the questions of the study. The study concluded that the Palestinian national project turned into different factional projects, after the PLO abandoned the armed struggle and recognized the State of Israel on the land occupied in 1948. The study concluded that the reasons and factors that led to the retreat of the Palestinian National Project relate to the Western support for the occupation and the field reality that was imposed by force, the Arab and Islamic abandonment of the liberation of Palestine, the exclusion of the military option in favor of the political option, and the Palestinian internal division and rivalry. The study recommended working to change the existing reality, through a comprehensive national reconciliation program, based on political partnership, in which the political vision and resistance unite, in addition to restoring the Arab and Islamic dimensions of the Palestinian cause to save the Palestinian National Project, which is the liberation of the Palestinian land with its known historical area.
