Talk politics.

Actually, unless one is fighting the equivalent of Shaka Zulu with helicopter gunships and M-1 Abrams, genocide is sharply *im*practical. It tends to cost the country doing it any attempt at good PR, it tends to sour relationships with the locals and lead to guerrilla insurgencies....the Nazi embrace of genocide proved impractical enough to the point that Hitler's belief in his own ideology did more harm to the Nazi cause than the USSR itself did.
