I am not American but given Germany's own role in much of what is going on in Gaza and the West Bank, the weapons shipments to Israel, (no 2 supplier after the US) and the diplomatic cover it gives to Israel, there's a lot Germany still needs to reflect on today.

Hint: The lesson was supposed to be that genocide is bad, period. Not that it's ok as long as it is some of the descendants Germany hurt doing it this time.
