You need ‘courage’, according to Rudd anyway:

Prime Minister Kevin Rudd has called for world leaders to show political courage at the climate change talks in Copenhagen in three weeks' time.

"What's required is a bit of political courage for everyone collectively to step up to the plate, put behind the familiar, put behind the fears and concerns of the past and embrace instead the opportunities of the future," he said.

"We're at one of those crossover points in the world, one of the crossover points in Australia.

"Let's rise to the challenge rather than simply succumb here at home and abroad to the politics of fear."

The ability of these guys to convince themselves of anything always amazes me.
