masters in IR vs masters finance / CS for working in a counter terrorism field

<p>I have been interested in counter terrorism for the longest time and I see all these organizations (FBI, NSA, etc) that have masters in international relations as a desired degree. I guess I always thought a degree that is more technical like finance or computer science would be more desirable over IR. What exactly does IR have that would make them so marketable for a counter-terror career?</p>
