If you take over a country by force, use the natural resources, enslave or subjugate the native inhabitants, and continue to plunder and manipulate it into modern times why should anyone care about hospitals, roads, rail, airports, etc? Gee thanks for all that, we will forget about the genocide, disease, and plunder.

Americans fought the American revolution over taxes and Britain housing soldiers in their homes. They did not care about the civilization that had been built by British pounds and protected the British military. It is sort of like Robert E Lee stating slavery was for their own good because at least they were not in Africa.

There were no nuances, only excuses. How to you negotiate with invasions, slavers, and those who support them? There is nothing moral to negotiate. They have to be defeated and removed from power.
