It is always dangerous to evaluate policy based on speeches like this. These speeches are about what the administration wants the public to think, which is only sometimes reflective of what is actually happening. But since any evaluation based on something other than public statements would amount to conjecture, I will comment on what we have.
This speech betrays some fundamental misconceptions of what is going on in Afghanistan, or at least does not present plans that could reasonably be taken to deal with the real situation on the ground.
