Why is the 1948 Arab-Israeli War called the War of Independence in Israel?

In Israel, the 1948 conflict is referred to as the War of Independence because it marked the successful establishment and defense of the State of Israel as a sovereign nation.12

Following the United Nations partition plan of 1947, the war began as a civil conflict and escalated into an existential struggle against invading forces from neighboring Arab states immediately after Israel declared its independence on May 14, 1948. By the time armistice agreements were signed in 1949, Israel had secured its existence, gained international recognition, and established sovereignty over a significant portion of the former British mandate of Palestine.312

Conversely, the same conflict is known among Palestinians as the Nakba (or "the Catastrophe") due to the mass displacement and refugee crisis that resulted from the war.314
