Whatever the conflict, I find it tragic when the history of a country is destroyed.
This happened in WW2 in Germany (e.g.Dresden) and is even now happening in the Middle East. Absolutely no society has the right to erase history for ever. The past is what made us now. We are part of that history. People, whatever their backgrounds, are vandals if they try to wipe out the past.
