While I don't agree with the parent comment, 20 years is just nowhere enough for his strategy. Mullah Omar himself was alive for almost half of those. Something like 50 years where the old regime leaders completely vanish can only work. Again I am not saying whether it is practical or whether it is even a good idea at all.
