It just shows you that no matter who is in the White House, our republic--with all its awesome and high-priced might--remains at a disadvantage when it comes to asymmetrical warfare.
What do you do if you're the Taliban, you're armed with rocket-propelled grenades and maybe some old Enfield rifles the British left behind back in the Nineteenth Century, and you're fighting a foe who has precision missiles that can rain down destruction from the sky with no advance notice, obliterating an entire crowd?
You make sure the crowd he obliterates is the wrong one.
Remember, this battle is for hearts and minds, not body counts. You use jiujitsu, turning the aggressor's own bulk and momentum against him. Enough of these little mistakes, and pretty soon the whole country sees you as the heroic defender of innocent women and children.
What are a few thousand more deaths in a country that has suffered so much already, especially if they serve a strategic goal? The locals don't know the Twin Towers from the Doublemint Twins, and when you say "terrorism," they look at all the bodies of their friends and loved ones that need to be buried.
