Question: When did most of the land called palestine became the country of israel?

context: Soon after the UN resolution, less than half a year prior to the expiration of the British Mandate, large-scale fighting broke out between the Arab and Jewish communities in Palestine. By the time Israel declared its independence on 14 May 1948, the result of these five and a half months of fighting was, according to historian Benny Morris, a "decisive Jewish victory". On one side, the "Palestinian Arab military power was crushed" and most of the Arab population in the combat zones was fleeing or had been driven out. On the other side, the "Haganah transformed from a militia into an army" and succeeded "in consolidating its hold on a continuous strip of territory embracing the Coastal Plain, the Jezreel Valley, and the Jordan Valley". The Yishuv (the Jewish community and its "state-in-waiting"-type organisations) proved it had the capability to defend itself, persuading the United States and the remainder of the world to support it and the "victory over the Palestinian Arabs gave the Haganah the experience and self-confidence [...] to confront [...] the invading armies of the Arab states."
