That historical guilt and awareness are noticeable in Germans and Germany. Their unconditional support of Israel is literally one of the consequences. So was their massive support for refugees.

They are really way stronger in admitting their country crimes the other countries I know about who generally like to pretend none of that ugly stuff was happening.

Shame on you! You turning it upside down, Germany think of them self as the worst war criminal ever (and forever) and that's is why the dont allow themself to ever criticize Israel whatever they do.
