The article is talking about two things at once and trying to pretend they are the same thing. The us hit the military base with a tomahawk missile, and the school was hit by a missile from "nooneistakingaccountabilityville". They are trying to act like the US hitting the military base proves that they also hit a school like a week ago.
So your analysis is that the US hit a few meters away with a missile, then another missile hit a few meters the other direction within minutes, but we can't know who did that?
