As you say, "ongoing treatment". The past is still present. Just because our (US) myopic society places plaques on any building over 100 years old and calls it "historic" does not mean that we get the right to say that something is "too old" to be rememberd and corrected. Native American's had histories going back, in many cases, thousands of years and for them much of the destruction was relatively recent and they have not forgiven or forgotten. Heal the past, prepare for the future.
