What if……

Something I have always wanted to ask:

During the Falklands war, what if the Argentine bombs that actually hit British ships had infact exploded. ? Would that have changed the course of the war. ?

If I am not mistaken atleast 7 British ships ( not sure exact nos.)were hit my bombs that were dropped at a very low level by the Argentines and did not explode as they did not have time to arm themselves. Lets not forget the British Ships caught fire very easily and did not have effective damage control mechanisms.

Also what would have happened if the Argentines had concentrated their attacks on the British cargo vessels like the Canberra instead of going for the picket destroyers ?
