He never promised to end drone strikes. In fact I believe he emphasized drone strikes even then in order to shift away from American "boots on ground" and the then-current policy of using JDAM bomb strikes (which are even more dangerous w.r.t. collateral damage).

You're quite right, actually - he didn't promise anything about drones - as at that point they didn't officially exist, most likely.
