It's tough to criticize perpetrators of war crimes.  For example, "...anyone who is guilty of the types of war crimes against innocents," without implicating our friends and allies is hypocritical. The coalition aircraft which have been bombing in Iraq and Syria over the last six years have killed and injured many innocents. The whole issue is complicated by with whom should the west support in Syria? Air strikes against Assad aids the "rebels" led by the al-Qaeda connected al Nusra Front. Aiding the rebels against Assad is pitting Sunni Islamists against the Shiite (Alawite) government of Assad. Things are a complete mess in the Middle East and unfortunately the west's interference in the 2003  invasion of Iraq is the underlying cause.
