If your enemy is superior, evade him; if equally matched, fight him; Sun Tzu.
It has nothing to do with lacking in the manhood department, it's just good strategy.
Exactly! It would be suicidal for the terrorists to engage any modern military ......quick suicide. Thus they resort to other types of attacks.
With that said though, I wish the terrorists feel 'offended' and try to engage our forces directly (and thus get mowed down). Who knows, these terrorists are not exactly brain-scientists! They may fall for it (I doubt it, but one can hope).
