And now this.
Make no mistake: the U.S. had no alternative but to fight the war in Afghanistan. We had to get rid of the Taliban government, which sheltered bin Laden and provided a sanctuary for al Quaeda and other such groups. And once the Taliban was deposed, to allow it back into power would have undone everything we accomplished.
But you can't help people who won't be helped. We learned that lesson much later and much more painfully in Vietnam. President Obama- who, by the way, supported the Afghan war all along (as did Vice-President Biden, despite his fib in the debate with Paul Ryan) is right: we need to get out as soon as is practical.
