  We argue that resonant friction has a dramatic effect on a disc whose
rotation direction is misaligned with that of its host nuclear star cluster.
The disc's gravity causes gravitational perturbation of the cluster that in
turn exerts a strong torque back onto the disc. We argue that this torque may
be responsible for the observed disruption of the clockwise disc of young stars
in the Galactic Center, and show in numerical experiments that it produces the
observed features in the distribution of the stars' angular momenta. More
generally, we speculate that the rotation of nuclear star clusters has a
stabilizing effect on the orientation of transient massive accretion discs
around the supermassive black holes residing in their centers, and thus on the
directions and magnitudes of the black-hole spins.
