The United States cannot simply walk away from the plain meaning of the Budapest memorandum and leave Ukraine in the lurch.
The memorandum begins by referring to the letter of “100 liberal American Jewish leaders.”
early 15c., from Latin memorandum "(thing) to be remembered," neuter singular of memorandus "worthy of remembrance, noteworthy," gerundive of memorare "to call to mind," from memor "mindful of" (see memory). Originally a word written at the top of a note, by 1540s it came to stand for the note itself. The Latin plural is memoranda. Cf. also agenda.
