Oh please. That tired old cliche is so lame, especially when misapplied, as it often it. What we are doing in Afghanistan is not "wrong" so your silly equation is thrown out the window. It must be nice to sit back in Australia, thousands of miles from the action, and critique how the Americans defend themselves (and the world) from terrorist scum. I wonder how you would feel if Melbourne or Sydney came under the kind of terrorist act that New York City sustained on 9/11.
For starters, I wouldn't want to 'nuke' a country without first finding out if those responsible were there, as you originally posted.
