The subjugation (or conquest) of Iraq was a necessary consequence of the military campaign. That's what subjugation, conquest, etc, are.
These are not words with pleasant connotations, however. And therein lies a major source of doublethink: we want to (in effect) conquer a country without actually conquering it (war without warfare; the bad guys lose, but everyone still wins and goes home happy). In the dream scenario, we defeat one faction militarily, some magic happens, and then we end up with West Berlin.
