You misunderstood. Attacking civilians is bad in any context and strictly illegal. Declaring war then attacking government, military, and critical infrastructure after such a declaration is quite different from flying a plane of civilians into a civilian building out of nowhere. Equating the two is as disingenuous as comparing a loan shark beating someone for non-payment to someone getting evicted.
