I partly agree with you. However, all of those trillions of dollars the US government spent in Afghanistan were flushed down the latrine. What do we have to show for it now? What did we purchase and do with all of that money? A county that is 60+ years behind, as far as its infrastructure, what did we do to help them? The culture is still stuck in the middle ages. The US could've transformed Afghanistan into a more modern, industrialized country, with more democracy and civil rights. All of those trillions of dollars went into the coffers of the Military-Industrial-Complex and its corrupt, cronies in the US Congress. The cabal in Washington in the pockets of the "defense" industry, made a fortune and the Afghans didn't benefit at all, especially the women and children of Afghanistan. They're in the same exact dismal predicament they were in before the American invasion and occupation.
America could've transformed Afghanistan by modernizing it and the people would've fought tooth and nail to stop the Taliban from taking power. The whole country would've fought till the very end, before allowing these barbarians back in power, because they would've had a taste of normalcy, freedom, and modernity. We deprived them of that, even after spending trillions of dollars and occupying their country for twenty years. Now what? We're going to starve them? Impose economic sanctions, freeze Afghanistan's assets in European banks, and make it impossible for the people of Afghanistan to live (eat, have access to healthcare, educate their children..etc). We're now causing them further pain and suffering, by allowing politics to starve them, and keep them from receiving the medical care that they need and providing their children with at least a basic education. Literacy is very important, almost there with food and healthcare.
