Ignore the last line in parentheses for my prior post; I misread the year when looking up the dates in question. Israel’s admission to the UN was three days prior to the first anniversary of Israel’s declaration of independence. (Mea culpa.)
The overall point is unchanged: recognition of one’s sovereignty as a nation does not necessarily hold because of the outcome of a given war. The general criteria are: a settled population, a defined territory, a government, and the ability to enter into relations with other states.
(Somewhat ironic, given that much of the trouble in the Middle East is precisely over the question of what counts as a “settled population”.)
I should correct a minor error from my #42 where I incorrectly stated, "Israel declared independence, and two hours later the United States formally recognized the State of Israel and established diplomatic relations."
It appears it was 11 minutes later, as shown below.
On December 11, 1947 it was announced that the British Mandate would end on May 15, 1948. Eleven minutes after Israel declared independence, President Truman officially recognized Israel.

U.S. President Harry Truman was the first world leader to officially recognize Israel as a legitimate Jewish state on May 14, 1948, only eleven minutes after its creation.
Harry Truman acted on May 14 Washington time which was May 15 Israel time.
