Was imperialism (empire building) by the French, English, Spanish & Portuguese a positive OR negative thing in the Americas? WHY?

Imperialism impacted societies in countless negative ways. It led to slave trade which then led to social discrimination around the world. It also damaged the cultures and created disunity among the natives. Last but not least, imperialism stripped countries off their natural resources and left nothing for the natives.

It helped develop global defense support.

With over 650 military bases in 38 different countries, American Imperialism has helped give the world some level of defensive support, protecting people around the world during conflict. This is by providing training, support, equipment and other resources
