McChrystal's admission that the Taliban are "not finite" must be held up for inspection -- first of all by General McChrystal himself. For what he subliminally recognizes is that the problem is not a defined group -- the "Taliban" -- but rather all those who join, or support those who join, any of a hundred or a thousand similar groups. And indeed, the enemy is not only those who support, directly and indirectly, Muslim terrorist groups that are engaged in Jihad -- that is the "struggle" to remove all obstacles to the spread, and then the dominance (in places where it has already spread) of Islam. In countries of Dar al-Islam that means purifying the practice of Islam, removing those elements that those inattentive to, or insufficiently moved by, the dictates of Islam, have muddied its pure serene. In short, this is scary sh!t.
