To be fair, they didn't have the capability to traverse oceans, however they did in fact "make war, enslave, oppress, or kill each other" for whatever distances they were able to travel.  Which always makes me wonder, how far back does restitution go?  Just whites for aboriginals or will certain aboriginal nations have claims against other aboriginal nations some of whom were only too happy to join up with the whites against their neighbours.  I have no doubt that aboriginals were, and continue to be, mistreated and that there needs to be restitution.  However when people look to an imagined utopian past, I don't see how grievances and injustices can ever be overcome.  We can only move forward and that won't happen if some groups seek to erase the last 450 years.
