Bush, the better half of the Dumb and Dumber Presidents, made a huge mistake with Afghanistan. Unlike World War II, and the actions taken by the Allies, Bush attacks a country because of 9/11 with zero objective in mind. Second, once there and realizing they are in the what next stage, they were utterly clueless.
That is when Bush & Co. come up with nation building a muslim nation that has NOT been subdued or defeated like Germany and Japan were in WWII. Far from it. And the USA began pouring trillions of dollars of its treasury into this godless nation.
What Bush should have done is destroy every city above a certain population. All of them. Using nuclear tactical weapons if necessary, but destroy 80% of the population, in a single day, and turned to the world and say, attack America, and you die. Had we done that, stinking France, Germany and Russia would never have uttered a word. And we would not have lost one American in that godforsaken land. And leave them to rot, with not one penny for rebuilding.
Unfortunately, because Bush was totally incompetent, America was set on a path of lost treasury and lost American lives, and for what?
The Taliban, ISIS and al Qaeda are just as strong as they ever were in Afghanistan. I say it is not too late to kill them all, with the exception of two cities. Yes, I will say it. Leave the two cities that have a population loyal to the government, and destroy the rest. Problem over.
