all of the other major powers are peaceful and not trying to take over other countries except for Russia. Minor countries do have violent civil wars and a few may even have plans to take other countries which are relevant to themselves. And the Arabs also. I do not consider any Arab country to be a major country except in oil production.
What are you talking about ?
USA and UK plus many other NATO countries and “democratic” allies were front and center in all of Serbia/Kosovo, Syria, Iraq, Afghanistan, Libya.
In every case they bombed and/or had troops on the ground and attempted to forcibly depose the ruling government, and in Serbia, they also severed a province, and altered the borders.
Only in Syria were they not successful in creating Regime change.
