I think the Spanish (not really"white") accomplished a lot during their rule. I don't know that I'd say the Romans or Greeks or Syrians or Ottomans or or ++ made accomplishments without breaking or exploiting others though. It is true white Americans seem to think it's been a long time that they've been in power and this is a forever thing. The USA assisted with WW2 and has been riding that through the last ~75 years, despite basically losing every encounter since.
