picture the scene:
terrorists release a biological agent at the heart of new york - lets say an ebola/flu gene splice virus that is airborn.
half the population of new york is killed.
the terrorists proudly proclaim on al jazera they hail from saudi arabia, it is also well known that this group has strong ties with the saudi royal family, and have in fact been funded by them
obama does what ?
not to mention - had this new policy been in place for pearl harbour - you may not have beaten japan, or at least not been able to join forces with the allies fighting in europe - the world would be a very different place today.
