Seems like the goal change in the middle of war. After 9/11 the USA was pretty much determined to destroy every other groups which is the threat to the USA that is the reason why USA invade Afghanistan in the first place. The USA never able to demolish the network, they manage to slow the process and have disturbed their presence to some extent, but they never manage to exterminate them. After spending 20 years on the field, they never fully crack the networks of this Al Qaida sure they might have destroyed thousands of networks, but it does not matter unless it's fully destroyed. Anyway if you want to look at the objective which been completed then be my guest, for me, I am continuing to look at Trillion of dollars Tax dollars has been wasted on the war which have not been won by the Nato and the west.
