The LHAASO Collaboration has recently reported a measurement of the diffuse
gamma-ray emission from the Galactic Plane at energies between 10 TeV and 1
PeV. While this emission is brighter than that expected from cosmic-ray
interactions in the interstellar medium alone, we show that the intensity,
spectrum, and morphology of this excess are in good agreement with that
predicted from the "TeV halos" which surround the Milky Way's pulsar
population. These results support the conclusion that TeV halos dominate the
ultra-high-energy sky, and that these objects convert ∼5% of their total
spindown power into very-high and ultra-high-energy photons
