The expected luminosity, energy spectrum and chemical composition of cosmic rays from Galactic GRBs, most of which do not point in our direction, can explain the observed properties of Galactic cosmic rays.Cosmic rays above the GZK cutoff will be discussed in a separate publicationAstrophysicsHigh Energy Physics - Phenomenologytext
