Yes they can. The Taliban is muslim. The taliban is organized, the taliban is the enemy.
That's obvious. But it would be wise here to explain why. The Taliban is an organization with an authoritative administrative social structure, and regaining control of Afghanistan is an official administrative policy of the organization. Think corporation. They're a corporation, an organized body with a central administration and command structure.
Anyway I don't see how you can claim that the muslim community does not an possess an organized structure.
The Muslim community does not possess a common corporate structure. Look at the Christian Faith. You have the Roman Catholic community with the Pope at its head. It's not just a loose-nit community but an incorporated organizational body with a to-to-bottom organizational structure. The Anglican Church likewise, with the Queen of Canada at its head. I'm not as familiar with the organizational structure of the Baptists, though I believe they have a few separate administrative bodies. If I'm not mistaken, the Southern Baptists have their own independent structure from others. I know the mormans have a common organizational structure with a common administrative body, as do the Jehovah's Witnesses. Certainly any official policy adopted by such an organization is assumed to be accepted by the official membership of that organization.
Muslims, like Christians, are split among various groups, each with their own independent corporate structure.
How much more clearly than I explain it? As such, official policies adopted by any particular Muslim organization apply only to their own membership, which does not represent all Muslims. But there is no one single administrative body in the world that is accepted by all Muslims.
Thus while Al-Qaeda can make policy decisions for its membership, it has no power over non-members, any more than the Pope has control over non-Roman Catholics.
