The idea that the war could have been ended any other way is Military Industrial Complex propaganda. It's a complete and total fabrication that relies on the ignorance of people to believe that just a little more war and death would magically create a stable government.
The Afghan government was always going to collapse to the Taliban. 10 years ago, 10 years from now.
There was no end to this war where the Afghan government resisted the Taliban.
And now you claim that the military industrial complex is happy about the end of the war, when they used their control of the media to throw a two month long tantrum? Ridiculous.
How funny that you in one breath bemoan "region destabilized by American hands" and in the next promote neo-colonialism and forever war. You stand for nothing. The Afghan people deserve to rule themselves and if they want an Islamic state, then your bigotry against their self-determination speaks volumes about your concepts of colonialism and your desire to be their white man savior.
