The United Nations General Assembly.

On November 29, 1947, the United Nations General Assembly adopted UN Resolution 181 which specified that Mandatory Palestine would be divided into an Arab State and a Jewish State. However, the plan was only actualized in May of 1948 when the State of Israel declared independence according to the terms prescribed by UN Resolution 181.

No.

In 1947, the United Nations, not the United States, adopted a plan calling for the division of the British Mandate of Palestine into a Jewish and Arab States. The United States supported this Resolution but did not "adopt" it.

The UN Human Rights Council was established on March 15, 2006 when the UN General Assembly adopted the resolution A/RES/60/251.
