No Combatant is Innocent in War
Expanding on my previous post, here is an example of what happens when people refuse to see evil when it's perpetrated by people they view as human.
After every terrorist attack there is usually a great deal of outrage at the fact that the attacker(s) targeted and killed civilians and rightfully so. However, when terrorist attacks against civilians are perpetrated by "their" side they're willing to either justify the action at necessary or unavoidable or they throw the entire incident down a memory hole:
Air strikes carried out by the US and its coalition partners in Syria have killed the highest number of civilians on record since the bombing campaign began, a war monitor has said.
A total of 225 civilians, including 36 women and 44 children, were killed in the period between 23 April to 23 May, the UK-based Syrian Observatory for Human Rights said.
No combatant is innocent in war.
Middle East attackers have killed a lot of civilians in the United States and Europe and the United States and its European allies have killed a lot of civilians in the the Middle East. Unfortunately, people living in the United States and Europe have a tendency to look the other way when their militaries kill civilians. I'm sure that a lot of people in the Middle East also have a tendency to look the other way when their militaries kill civilians. Justifying or ignoring the crimes of your tribe while condemning the same crimes of another tribe is common human behavior, which is also why we can't have nice things.
