In Australia the Battle of the Coral Sea, which was in no way a decisive victory for either side, is celebrated as "the battle that saved Australia", it's somewhat surprising that Midway doesn't loom larger in our historical awareness. As several well informed writers have speculated, without the US victory a re run (or two) of the Coral Sea battle might not have been out of the question, and, if so, might well have produced a less favourable result for the Allies.
A little acknowledgment in Australia would not go amiss, but then the country is preparing to receive the Japanese Prime Minister on an official visit. I have no problem with rolling out the red carpet for him, but I don't believe that potentially unpalatable facts about our past history should be swept under that carpet.
Information about Midway
As well as the Wikipedia article I've linked to above, there's a wealth of (mostly US-based) information on the internet about the battle. A Google search will reveal a substantial chunk of it.
