you could die tomorrow in a car accident you know? life has NO guarantees and I also believe that there are better palces to attack, like Robo said - but again, raising the question: why did the insane bombers in Bali choose that specific club? because they want to cause fear and say: we are going to get you where you LEAST expect it, so I understand your girlfriends fear.
Still that reason is not going to prevent me from having a good time. I could well understand it if you guys were headed for Bali, but I think that schould the war start, it will be over with quickly.
All they want is to wipe out saddam and raise a new democracy and government with justice.
So convince your girlfriend to go and relax....I don´t see any need to fear things even though I understand her very well.
