Iains,
I would have severe reservations about the attribution of casualties

Syria would have reported any.

I know that the coalition and MSM like to emphasize surgical strikes, but even with smart weapons(and what percentage are dumb weapons?) mis targeting occurs.
How many surgical    strikes hit schools, buses,hospitals, generating capacity etc ect.

Again, Syria would have reported any.

The idea that civilians do not get killed by all sides in this conflict is preposterous.

It is preposterous to suggest that Western strikes have killed civilians in this conflict.
There has only been one previous strike against Assad. Last year an air base was hit.
Putin's and Assad's air strikes have caused civilian deaths in this conflict.

The strikes you now refer to were not against Assad or his regime. They were part of the war against ISIS, and not relevant to this discussion.
Syria was also fighting ISIS.
