White House Statement Announcing Recognition of the Government of Israel.
ON October 24, 1948, the President stated that when a permanent government was elected in Israel, it would promptly be given de jure recognition. Elections for such a government were held on January 25th. The votes have now been counted, and this Government has been officially informed of the results. The United States Government is therefore pleased to extend de jure recognition to the Government of Israel as of this date.
