It's a truism -- pounded into our noggins morning, noon, and night -- that we continually underestimate our Islamist enemies. We think that we'll defeat them in a few months, we think they'll give up, we think they'll just go away. And of course, we're continually frustrated by their utter refusal to conform to our foolish stereotypes.
But you know what? The jihadis relentlessly misunderestimate us, the West... and they underestimate us far more egregiously and foolishly than we do them.
Never thought about it?
