Yeah, the whole thing is based on armchair assessments to begin with.

1) I dont think all the involved military leaders are such cartoon villians that they would intentionally strike a school full of kids

2) I especially dont think they would do so with the intent of a follow up strike exclusively for killing the first responders to the atrocity from (1)

Delivering two bombs to a military target doesn't seem unreasonable. The fact that two missiles struck the school is not evidence of (1) OR (2). If there were significant intentional delay, that would change my assessment. There doesn't seem to be, in this case.
