In the first part of this note we argue that ten dimensional consistencyrequirements in the form of a certain tadpole cancellation condition can besatisfied by KKLT type vacua of type IIB string theory. We explain that a newterm of non-local nature is generated dynamically once supersymmetry is brokenand ensures cancellation of the tadpole. It can be interpreted as the stresscaused by the restoring force that the stabilization mechanism exerts on thevolume modulus. In the second part, we explain that it is surprisinglydifficult to engineer sufficiently long warped throats to preventdecompactification which are also small enough in size to fit into the bulkCalabi-Yau (CY). We give arguments that achieving this with reasonable amountof control may not be possible in generic CY compactifications while CYs withvery non-generic geometrical properties might evade our conclusion.
