The systems that committed those injustices and crimes against humanity are alive and kicking. The processes and motivations that led to those matters are still present. The only thing that changed is that there is no more motivation to commit such atrocities again, surely those will come back.

Beyond that, I don't see why we should excuse past crimes. All that motivates is for future crimes to be done faster so that the moral high ground can be restored then.

So if only now matter you mean that nobody should pay their debt? Cause i know a country who goes to extreme length to get back his money... So which was in it? Both ways i guess.

By the way if you interested the US is STILL in Irak, Donald Trump PARDON the CEO of Blackwater, US is supporting the war in Yemen, look it up it goes on and on....
