'Cowardice', according to Colin Powell, is the refusal to injure thousands of innocent civilians living in Baghdad in order to promote US oil interests in the Middle East. The corollary is that 'bravery' must be the ability to order the deaths of 100,000 Iraqis without wincing or bringing up your Caesar salad.
I suppose Tony Blair is 'brave' because he is willing to expose the people who voted for him to the threat of terrorist reprisals in return for getting a red carpet whenever he visits the White House, while Chirac is a 'coward' for standing up to the bigoted bullying of the extremist right-wing Republican warmongers who currently run the United States.
In the same vein, well-fed young men sitting in millions of dollars' worth of military hardware and dropping bombs from 30,000ft on impoverished people who have already had all their arms taken away are exemplars of 'bravery'. 'Cowardliness', according to George W. Bush, is hijacking an aircraft and deliberately piloting it into a large building. There are plenty of things you could call that, but not 'cowardly'.
