Franklin Roosevelt actually said...

"Such list shall be known as 'The Proclaimed List of Certain Blocked Nationals.'"

"Any person, so long as his name appears in such list, shall be deemed to be a national of a foreign country."

"By virtue of the authority vested in me as President of the United States, it is hereby ordered as follows:"

"Officers of the Foreign Service shall familiarize themselves with those provisions of the laws of the United States which relate to the acquisition and loss of American nationality."
