I think Miss Japan deserved to win. USA sure didn't deserve to be in the top 5, not after she fell. What an insult to the other 4 contestants who didn't make the final 5, yet managed to do their walk without falling on their keister.
I don't care if she smiled like a trooper after her fall, there have been other contestants in past Miss Universe competitions who have stumbled and NEVER made it past THAT round.
