I dont think QE2 travelling on western airlines to Australia faces the same risk of terrorist attacks, as leaders of Pakistan traveling on commercial PIA flights to the Middle East. Hopefully, some of the money for such flights is paid by US assistance to Pakistan on the war of terror. I agree with you that unscrupulous individuals will take adavantage of tragic situations.
If the threat was that grave he should have just 'avoided' this lavish muft umrah trip which cost so much money. I am sure Allah would have rewarded him without his sarkaari umrah.
