So, once again we have an answer that goes back to everything between the 16th to 17th century. I am explaining this in every post, that there is a big difference between then and today. At that time almost all countries were at war now and then to gain more land and power.
Today, we have a more developed society with all from better understanding to international organizations to deal with this. We are also more educated. What you are doing is comparing something we call colonization and settlement with thug, mafia and insurgency, which is something that today fall under criminal activities.
