Imagine being so beyond time and still believe in a empire. Free humans neither bow down to a emperor, party, club-boss, doctrina, czar, tycoon....or be lead by any other cult figure.
That's just the point. We are way past eras of colonisation or subduing a people by waging wars. That savagery has gone with the 20th century and we've been more better since then, looking out for civilised means to archiving a goal.
I can try to see reasons why a nation would wage war when peaceful resolutions isn't reached in order to protect its borders from invasion but, not for the purpose of editing the maps and sourcing for resources.
Talking about slavery and a people, I think Africa ought to say the most here but no, it's history and trying to do anything other than restitution and forging ahead would be issues of course, aggression and retaliation. We don't need these in our world today.
In my opinion none of the Ukraine and Russian ally has really tried to save them from war .. .
The have accelerated the war and created so many problems for the world. Now the whole world suffers the inflation created by them. Everyone is in the state of panic these days. Thanks to the superpower for creating disasters in the world around.
