I used the Bhutto example to show the fallability of Pakistani security. Point I am making re India is that terrorist causes in India revolve around Kashmir. In Pakistan the anti western movement would be much larger.
You seem to have gotten it into your head that every other terrorist in Pakistan is out to kill any American/European/Australian guy he meets...
I can understand why the Aussies are reluctant to tour. It is because of previous precedents set by their predecessors and somehow, a stigma has been attached to touring Pakistan (wrongly, IMO). So I can understand why those guys are so reluctant but honestly, there is no way to defend it as the right thing. The best thing you can say about their concerns is that they are perhaps understandable, but no way are they justifiable.
There are places in India where the threat is just as high as there is in Pakistan and yet Aussies don't have a problem because of two reasons:
a. There is no such stigma attached with India as there is with Pakistan (mainly based on wrong perceptions, if I may add that)
b. Money. Moolah does talk and they all know that there is a good amount of money to be made if you are an Aussie cricketer touring India. The Ads, the IPL contracts and now even Bollywood cameos being on the anvil makes it a more viable proposition and they are willing to take that chance against security advice.
At the end of the day, the blame should sit with CA for not being man enough to send the players (whoever are ready to play) on tour. I am sure if there is one tour by an Aussie team to Pak, even the players who have concerns will be ready to tour the next time.
