About the same goes for those soldiers who want land.

You see, there is a difference between the motivation of the leaders and the followers. The leaders started every war because of power. The question is why people followed them and that reason was only in some exceptional cases religion. Not even a conflict like the one in Northern Ireland is because of religion.
