With the tenth anniversary of 2001-9-11 coming in two days the media is again talking about the Bush Doctrine as if they know what that means. Doing that makes them feel smart, but if they had to define the so called doctrine all that assumed intelligence would evaporate. That's because, as Wikipedia says, "various related foreign policy principles." In other words, there is no distinct "Bush Doctrine."
The media idiots think it means preemption. As Sarah explained correctly to that Gibson guy looking down his nose at her over his glasses... International law has always allowed preemption where a threat exists. You are not required to sit and take it until damaged.
