It goes back to the days when we were defending ourselves against the internal aggression of the Native American population, who we incidentally wiped out in the process. In the post World War II period, we've frequently had to carry out defense against internal aggression, that is against Salvadorans in El Salvador, Greeks in Greece, against Filipinos in the Philippines, against South Vietnamese in South Vietnam, and many other places. And the concept of internal aggression has been repeatedly invoked in this connection, and quite appropriately. It's an interesting concept, it's one that George Orwell would certainly have admired, and it's elaborated in many ways in the internal documentary record.

The principles of universal grammar provide a highly restrictive schema to which any human language must conform, as well as specific conditions determining how the grammar of any such language can be used. It is easy to imagine alternatives to the conditions that have been formulated (or those that are often tacitly assumed). These conditions have in the past generally escaped notice, and we know very little about them today.

So we know that human nature, and that includes our nature, yours and mine, can very easily turn people into quite efficient torturers and mass-murderers and slave-drivers...To the extent that the statement is true, and there is such an extent, it's just not relevant: human nature also has the capacity to lead to selflessness, and cooperation, and sacrifice, and support, and solidarity, and tremendous courage, and lots of other things too.
