New bombs would only stir the rubble of earlier bombs. Would they at least get the Taliban? Not likely. In today's Afghanistan, only the Taliban eat, only they have the means to move around.
US foreign aid is systematically diverted by those in power. This is the record of US foreign aid in just about every country we ever subsidize. Those with power, take the financial aid from those who are weak.
I'm sorry that the Afghans are starving -- yet another victim of Communist imperialism (this is not a flippant statement on my part, I really bear the average crippled Afghan orphan or destitute widow no ill will) -- but it cannot help to put financial assistance into a kettle from which the Jihadists of the Taliban skims the proceeds for their own benefit. Especially when the "kettle" in question is already so dry that even the Taliban are desperate to steal any financial aid they can get their hands on.
We created a monster. Now we have to kill it.
On the one hand, they can not be allowed to get away with this. Never mind that misguided Interventionist policies helped to install them in power, they have shown their willingness to commit mass-murder and must now be removed from power.
But on the other hand, I fear that the author of your piece may well be right in his observation that this will be no simple matter.
It's like I've said: I wholeheartedly approve of military action to annihilate those responsible. I believe that it is morally justified (and then some) and strategically necessary. But -- as I said above -- it seems to me that the complete elimination of the Taliban State as a political entity is the only operation which will burn out this cancer once and for all. And personally, I would like to hear some militarily realistic scenarios of just how we are going to do that.
