What is the message from the war of the worlds

Most contemporary analyses of The War of the Worlds compare it to European Imperialism and expansion; with their superior technology, the Martians (Europeans) invade the weaker nation of England (Africa, Asia, etc.) and dominate the "inferior" people with their military might. Wells showed how Humankind, believing themselves to be superior to all other creatures, can be reduced to animalistic survival instincts; in the same manner, European expansionists thought of other races as inferior, and considered their actions in those regions moral. If the Martians had no reason to consider Humanity as anything but inferior animals, they had no reason to spare them; using humans as cattle and food is similar to the enslavement of humans by other humans practiced around the world during past eras.
