There is no equivalence; on the one hand, abortion is an inherent evil, never to be justified in any case. War may or may not be just, but the decision is ultimately in the hand of civil authority, not the Church.

That is a nonsensical statement. By that "standard", every war launched by Nazi Germany and Soviet Russia were just -- just ask Adolf Hitler or Josef Stalin.
