The Belgrano sinking is still a HOT topic here in Argentina, and many people (mostly not in the military) think the attack was a war crime
Speaking only for myself, I have the same opinion as the Belgrano commander, Captain Bonzo: The Belgrano was a (proud) weapon system in a war mission, so she was a legitimate target.
Someone infra (below in latin) commented about the Argentinian navy performance (or lack of) in the South Atlantic War. About this service (my service) I only could comment the exceptional performance of
Naval Aviation (you could credit Ardent, Atlantic Conveyor and Sheffield)
Marines (BIM 5 - Marine Infantry Battallion nº5- at Tumbledown was considered the best unit of the defenders)
Submarine Force (ARA San Luis was active almost all the conflict, stalking the fleet and launching attacks in at least 2 occasions, even with innefective SST-4 torpedoes and a broken fire computer)
About the fleet, without means against nuclear submarines, what else could do?
Finally, no war is a football match, some of the posts in this thread are very disgusting.
