ALL conflicts are winnable, that's the nature of them. I thought the real trick was to be on the winning side though.
So, although Bob said the conflict is winnable, did he mention which side he thinks will do it? He has probably been briefed that one of the sides has ever increasing recruits, more and more gear, and are determined to win, but that they lack ellicopters!
Maybe he did nor hear the part where they talked about the coalition forces, or maybe in true noo labour style, he is just going with the side that gets the most media coverage
