Reply to "comment on 'Symmetry of Kelvin-wave dynamics and the Kelvin-wave cascade in the T=0 superfluid turbulence' "

The goal of the Comment by L'vov and Nazarenko is to refute my perviously published criticism of their mechanism of the Kelvin-wave cascade. It is important, however, that, in their Comment, L'vov and Nazarenko admitted that the Hamiltonian, from which they derived their mechanism, is not tilt invariant. This provides full ammunition to their critics, who believe that their mechanism is in conflict with the tilt symmetry of the Kelvin-wave dynamics and, therefore, is not valid for the real isotropic world.
