Airstrikes kill civilians

We are told that drone strikes have surgical precision.

We are told that intelligence is always checked before targeting people.

Afghanistan: US admits Kabul drone strike killed civilians

We are told lies.

These are extra-judiciary (i.e. sentence delivered without trial) executions (i.e. killings).  We usually call that murder.

Why is nobody held accountable?

Oh, I forgot.  We are.  By the families, friends and sympathisers of the victims, who hold us responsible for the actions of our military and governments.

Are you happy, being party to mass murder of innocent civilians, including children?
