Welcome to the human race. Every nation has arrived at its current boundaries through invasion and war. Some were were a little more polite about it than others, but it was still invasion.

Wanna know something? The indigenous peoples of every continent and country, committed acts of theft, invasion and warfare.

Native Americans, North and South, practiced warfare, slavery, head hunting, genocide, ritual sacrifice on horrendous scales .....and oh yeah, cannibalism when they were a bit peckish.

No nation or race is innocent. However, many of us have grown past it. Many have not. You do not even want to know what still goes on in Africa to this day.
