  We investigate the effective interaction between two like-charged rods in the
regime of large electrostatic coupling parameters using both Molecular Dynamics
simulation techniques and the recently introduced strong-coupling theory. We
obtain attraction between the rods for elevated Manning parameters accompanied
by an equilibrium surface-to-surface separation of the order of the
Gouy-Chapman length. A continuous unbinding between the rods is predicted at a
threshold Manning parameter of 2/3.
