The failure of Afghanistan by Bush is simple. It is the same lesson NOT learned in Vietnam. What is that exactly?
WHEN YOU GO TO WAR, YOU USE EVERYTHING IN YOUR ARSENAL TO DESTROY YOUR ENEMY!
We did not do that in Vietnam, and every military action since. The USA has been led by idiots since 1960, Trump the only exception.
How many movies have we seen where Americans work to secure a patch of ground in Vietnam only to give it up and leave via helicopter at some point? Too many!
Afghanistan, a haven for terrorists, and what do we do, occupy it PARTIALLY while the very same folks that protected al Qaeda remained in control of most of Afghanistan since we occupied it. Typical Bush idiocy. Had I been POTUS, I would have made the southern half of Afghanistan uninhabitable, without putting one foot on the ground.
Now they have ISIS in Afghanistan, and our media virtually never talk about it. When we pull out, which will be soon, ISIS will consume the Taliban, and Afghanistan will become the ISIS caliphate. We should warn both ISIS and the Taliban that should that happen, we will drop a dozen MOAB bombs on Afghanistan on their 12 largest populated areas, without warning. And if that does not end the nonsense, we nuke with tactical nuclear weapons any remaining strongholds. We have lost our intelligence on how to deal with an enemy.
As fas as I am concerned, the muslims have not answered for 9/11, not even close. But again, we had another idiot as POTUS. Now, we have an even worse fool as POTUS, and the damage this idiot will cause may well take the USA down permanently.
