That's a completely different argument again. Whether the tactics were used were correct, or effective, is a different from the question whether the operation should have been undertaken at all.

The large-scale ethnic cleansing was a deliberate reaction by Milosovic, it might be added. Presumably, he would also use this tactic in the case of a ground invasion (it would be far more disruptive to allied operations in the case of a ground invasion).

Before, we had small-scale ethnic cleansing and the occasional massacre. Should we have given Milosevic free hand in pacifying Kosovo after talks came into a deadlock?
