You ignored the important question.

Yes, I do.
You still haven't explained why you think a private military would somehow magically avoid profitable endeavours. They are Capitalists. I thought you loved Capitalism and

1. When was the last time that a foreign invasion was profitable? They look like huge money sinks to me.
2. If it turns it's back on it's customers, why would they continue to be it's customers?
