FDR: “It is ordered that all the hereinafter-described lands and waters... be, and they are hereby, reserved and set apart.”

Possession of any mine or mines taken under this order shall be terminated by the Secretary of the Interior as soon as he determines that such possession is no longer required for the successful prosecution of the war.

I would say the United Nations.

The work, my friends, is peace.

All Federal agencies are directed to cooperate with the Secretary of the Interior to the fullest extent possible.
