  In the first part of this note we argue that ten dimensional consistency
requirements in the form of a certain tadpole cancellation condition can be
satisfied by KKLT type vacua of type IIB string theory. We explain that a new
term of non-local nature is generated dynamically once supersymmetry is broken
and ensures cancellation of the tadpole. It can be interpreted as the stress
caused by the restoring force that the stabilization mechanism exerts on the
volume modulus. In the second part, we explain that it is surprisingly
difficult to engineer sufficiently long warped throats to prevent
decompactification which are also small enough in size to fit into the bulk
Calabi-Yau (CY). We give arguments that achieving this with reasonable amount
of control may not be possible in generic CY compactifications while CYs with
very non-generic geometrical properties might evade our conclusion.
