What is the longest-standing aspect of the conflict between Palestinian nationalists and Israel?

The longest-standing aspect of the conflict between Palestinian nationalists and Israel is rooted in the historical tensions and disputes that arose with the founding of the state of Israel in 1948. This event marked a significant turning point, as it led to the displacement of a large number of Palestinians, an event referred to as the Nakba or "catastrophe," by Palestinians. The struggle over territory, national identity, and political rights has persisted since that time, making it clear that the core issues of the conflict—such as borders, the status of Jerusalem, and the rights of Palestinian refugees—remain unresolved.

The reasons surrounding the founding of Israel are foundational to understanding the ongoing conflict, as they set the stage for decades of political, social, and military struggles. This historical context underlines why this aspect of the conflict is considered the longest-lasting and most significant. Other matters, like the Cold War's influence on regional dynamics or phases of negotiations, have created temporary shifts in the situation but do not address the enduring nature of the core conflict that began with the establishment of Israel.
