Terrible war crime during the conflict for the Falkland Islands?

for one thing, there is no such thing as a warlike limit. secondly, the belgrano was a war ship that was being used by the argentinians, therefore a legitimate target. third, the falkland islands are british sovereign territory not under the control of argentina. therefore, you invaded another country's property which the british had every right to remove you from the islands by any means necessary. that includes the sinking of warships, or combat in general. you lost get over it.
