Is it true that retrograde orbits are attained by launching spacecraft in the direction opposite to the planet's rotation?

By definition, a retrograde orbit is one that moves in the direction opposite to the rotation of the primary body, which is achieved by launching spacecraft counter to that rotational direction; no citation is needed for this fundamental orbital mechanics definition.

The analysis

The claim states a foundational definition in orbital mechanics regarding retrograde orbits. None of the retrieved papers directly address or evaluate the launch mechanics of attaining retrograde orbits, making this a matter of common knowledge.
