Argentinas military capability - or otherwise - has never been a factor in deciding whether there'd be more fisticuffs, for the Argentine government its a purely political calculation with purely political costs and benefits.
they have no interest in the technical correlation of forces because they aren't interested in the military result, only the political result.
them being skint also has no bearing on the matter - they are only skint in 'big picture' terms, they still have enough ready cash to spend on expendables like munitions, fuel, some spares etc.. and enough assets to use those expendables in a militarily limited, but politically driven, operation.
