Without Palestinian intervention then in our timeline, Israel declared independence from Great Britain in 1946 before Britain went into civil war. It was once a British colony known as the British Mandate of Eretz Israel in which the Jewish Agency for Palestine declared that the State of Israel should live on in life. Israel after independence was forced to go to war with Arab Nations. Egypt, Lebanon, Libya, Jordan, Saudi Arabia, Iraq and Syria went to war with Israel to liberate what Arabs call Palestinians with support from Cuba and the Soviet Union. Israel won all the wars with these nations but it is clearly unknown about another war or maybe a war of independence by Palestinians.
