If we select wisely, that simply means we prioritise our targets according to both urgency and strategic considerations. Which - guess what - is more or less what we're doing now. And if we keep intervening, that amounts to being the world's policeman. You can't police the world halfheartedly. It doesn't work. That's what led to 9/11.
Domination is as domination does. I can see you enjoy semantic games, but I'm more of a practical sort. So I'm calling it what is. A benign world government, securing peace, dignity and freedom for the individual of all the world, headquartered in Washington, DC.
Unless you'd prefer a "balance of power" between all this and its opposite: petty tribal wars, contempt for human rights, and brutal dictatorships. That is, the status quo ante in the sort of places in which we intevene. Moral equivalence is morally indefensible. It's the *real* simplisme. The ultimate non-thought.
Oh, and by the way: The Roman Empire and the British Empire both lasted an impressively long time, and traces of their influence remain to this day. If you're going to discuss history, do at least try to note the time scales involved.
They also both left the dominated parts of the world in better shape than they had been in to begin with. I should think that counts for something.
Also, to say that these empires destroyed their countries is quite a stretch. For all you know, they may have prolonged their lives.
