The answer would be A. In 1947, the U.S. and the Truman administration, under domestic political pressure, pushed for a solution and resolution on the Arab–Israeli conflict,
and in May 1948 the new state of Israel came into existence. This
process was not without its fights and loss of lives. Nevertheless, the
first state to extend diplomatic recognition to Israel was the United
States; the Soviet Union and several Western nations quickly followed
suit. No Arab state, however, recognized Israel.
