You know, the only reason the Damocles Gulf Crusade didn't result in the extinction of the Tau species as intended was because of Hive Fleet Behemoth, trouble within the Imperial crusade fleet with cooperation, the respect the soldiers of the Imperium (such as the Astartes) had for the Tau, and slightly because of the Tau's resistance. Now if the entire might of the Imperium, let's disclude all of the thousands of other problems the Imperium faces, and assume the Imperium only has to deal with the Tau, the Tau would be wiped out and exterminated as a species within a year or less. The Tau are quite lucky the Imperium does not consider them overtly hostile and as much of a pest as Orks are, and because 80% of the galaxy's problems must be dealt with by the Imperium, the Tau are able to expand.
