7 Taliban Insurgents Attack the Capital of Afghanistan

The L.A. Times reported today that 7 Taliban Insurgents attacked Kabul, the capital of Afghanistan. From the sounds of the article, the Taliban were quite successful, despite their small numbers versus our large numbers. Which begs the question, if we can't defeat 7 lowly suicide bombers in our Afghanistan established government's capital, can we ever stop the insurgency? Or has the collective conscious of America accepted the fact we are sustaining perpetual war? When we get reports like this from Afghanistan, it feels like we are beating a dead horse when asking if we can win. Or if that is our true goal? It seems it would take something the scale of D-day to search every cranny of Afghanistan to wipe out the Taliban. More likely the entire Middle East. The non-combatant casualties would be astounding. It looks like we are building towards this. The longer we continue to bomb innocent people, the more terrorist we form; the more terrorist we have, the more terrorist attacks we have; the more terrorist attacks we have, the larger force of troops in the Middle East we'll have; making a viscous cycle that cannot be broken. Since there is no evidence of us changing our foreign policy towards the Middle East, a full out D-day style invasion is a possibility we are working towards.

Let's hope I'm wrong.
