October 14, 1939 The Shame of President Franklin D. Roosevelt: 1933-1945

“None of the articles (e.g. Palestine Mandate and the American – British Convention of 1924) empower the Government of the United States to prevent the modification of any of the mandates. Under their provisions, however, this government can decline to recognize the validity of the application to American interests of any modification of the mandates unless such modification has been assented to by the Government of the United States.”
