International relations
The Hyde Park Agreement was lost in Roosevelt's papers after his death, and until the American copy of the document was found American officials were puzzled when the British mentioned it. The Quebec Agreement was an executive agreement that only applied to the Roosevelt administration, and the Senate had not seen the document. McMahon told Churchill in 1952 that "If we had seen this Agreement, there would have been no McMahon Act." The McMahon Act fueled resentment from British scientists and Churchill and led to Britain developing its own nuclear weapons.
