Both sides in the conflict are wrong and share the blame. However, it is usually with the stronger ones where the responsibility for de-escalation lies. Also don't forget the Afghans where Million have died due to conflict since 78 and millions more have been maimed and wounded.
Nothing with this thread, but it made me ponder on the idea of collateral damage (ie killing of civilians due to bombing/other mass destruction weapons) and how it fits within the Islamic jurisprudence. The prophet (PBUH) at multiple times in his life offered guidance on the issues of conduct of warfare. It seems to me that the various Muslim states in conflict with each other don't follow any of these principals. But I will have to do some research on this idea of collateral damage and if there are anything related to the subject anywhere.
