Newton is a consequence of Kepler's laws. Yes Newton covers inertia.

Kepler laws-rule are just observed patterns of behaviour,
that occur at very special conditions,
they do not have general validity needed for the law.

It is enough if mass ratio is not high enough,
if speed is too high
or if there are more than 3 objects,
to rule these rules out.

But as pattern of behaviour, they prepared the ground
to discovering the law, that rules over all this phenomena,
manifesting itself in special cases as Kepler laws.
