Ally or enemy? Do we still consider those that kill our citizens to be enemies. If so, they are enemies (with nukes.) We have a low opinion of Saudi Arabia for paying terrorists to leave their government alone. Why is it different that we do essentially the same thing with governments around the world, including Pakistan? Are the friends of our enemies our friends?
The world isn't afraid of offending America with actual threats. They have more than boxcutters. Will the first nuke of American soil be from Pakistan?
