Afghanistan is a big mess and there still are warlords controlling different parts of the country. There is much to be concerned about.
There will always be warlords controlling parts of the contry to some degree. They have a tribal system. Always will. The point is that we destroy the ones that are hostile, and make peace with the ones that are not. It's safer now than it has been in 100s of years.
How many warlords are fighting us? Yep, a couple have declared us the enemy....and thats why they live in Pakisatan and Iran.
