It is because of opium. If we were serious we could destroy the Taleban in a month. But we aren’t serious. And our people are dying because of that fact.
That’s only part of it. The biggest reason is that our “ally” whom we give billions of dollars in aid to, Pakistan, is providing a safe haven for the Taliban to train and recruit. America’s State Department under both Bush and Obama, somehow pretend that Pakistan is helping us and that lie is wasting lives and money in the third world sh1t hole that is Afghanistan.
