One factor of emotional intelligence versus the regular definition of intelligence as information we can use for national security is that we need to have the ability to perceive danger.  I have often heard the World Trade Center disaster described as a failure of imagination.  We could have prevented it, but no one could imagine it so when the intelligence pointed in that direction it was ignored.

This is a distinction we need to make, no matter what the job at hand, but in terms of homeland security, we are making judgements that could be a matter of life and death.  Intelligence, as we usually measure it, is about logic, making factual connections, being able to observe patterns, and so on.  Emotional intelligence is about having insight into the emotions of oneself and others and adjusting accordingly to meet one's goals.  All the facts in the world might not be very useful in assessing the risk a particular person poses, in acting in a way to disarm someone who is dangerous, or in understanding the motives of others.  I would bet on emotional intelligence every time!
