Australia unlikely to tour Pakistan.
I'm surprised there hasn't been much discussion on this topic. I personally believe that Australia would be safe to tour Pakistan. No cricketing (or any other sporting team) has ever been a target of terrorists in Pakistan. And of course South Africa and Zimbabwe just toured without a hitch. Having said all that though, I couldn't fault CA for being nervous. They're not from Pakistan so don't know true ground realities there. They see violence and bombings in the news and perceive a threat to their player's safety. I would be very sad if they didn't tour, but I would have to accept their reasoning.
