Conquest is necessary because if you take a conservative opinion that you should expect from the world what it currently gives you; and what it currently gives you is that a small minority of the world’s population lives semi-happily in the western countries; then the only way for the poorer countries to get on the same level of salaries is to take away those salaries from the west and make west the third world instead.

Every other argument you make is akin to a “what if”. I am speaking about how it _currently_ is.
