UN Resolution 181 had no teeth to create either a Jewish or Palestinian state. The Israelis declared independence and fought for it, just like we did.
Israeli Declaration of Independence
"The Israeli Declaration of Independence, formally the Declaration of the Establishment of the State of Israel, was proclaimed on 14 May 1948 by David Ben-Gurion, the Executive Head of the World Zionist Organization, Chairman of the Jewish Agency for Palestine, and soon to be first Prime Minister of Israel. It declared the establishment of a Jewish state in Eretz-Israel, to be known as the State of Israel, which would come into effect on termination of the British Mandate at midnight that day. The event is celebrated annually in Israel as Independence Day, a national holiday on 5 Iyar of every year according to the Hebrew calendar."
The Israelis declared independence and fought for it, just like we did.
