Just to be clear, i have absolutely nothing with the monarchy. To me, it's insane that we still have these institutions in this day and age. It just does not seem to be a huge issue that signifies something about national identity to me.
Well, they would be extremely hard to negotiate, of course; but attitudes towards Indigenous Peoples are better now than they were a century ago and whenever else the current treaties were created, so I'd expect a better deal for them in the end. If any treaty could be concluded at all. Indigenous Peoples would (rightfully) probably want more than any government would now be willing to offer (due to current population spread and economic consequences; the usual lame arguments), so actually getting new treaties might turn out impossible.You must be joking if the new treaties are going to better. Even all current governments have a hard time respecting the old ones.
