I agree with you wholeheartedly Phrog. Since WWII the percentage of posthumous MOH awards has been steadily rising until now where everyone who has received it for actions since the end of Vietnam has been posthumous. If you read some of the awards from WWII, Korea and Vietnam where the person lived, their actions were equally heroic to those who died in almost all cases. And almost every award of the MOH since 1941 is definitely deserved (except maybe MacArthur's, and a tiny number of others). There were even a few who lived when they did jump on the grenade, or drag a burning phosphorus bomb out of a B-29, etc.
As a comparison, there have been two awards of the Victoria Cross (one for the UK and one for New Zealand) and three awards of the George Cross (the non-enemy action equivalent of the VC) for actions in Iraq and Afghanistan and only one of the awards were posthumous, the rest survived the actions for which they were decorated. And both of those awards are just as prestigious as the MOH.
It is just a concerned observation, I hope it is not a permanent trend.
