  In this paper we discuss the theoretical difficulties in extracting $V_{ub}$
using the data from inclusive B decays. Specifically, we address the issue of
the end point singularities. We perform the resummation of both the leading and
next to leading end point logs and include the leading corrections to the hard
scattering amplitude. We find that the resummation is a $20\%-50\%$ effect in
the end point region where the resummation is valid. Furthermore, the resummed
sub-leading logs dominate the resummed double logs. The consequences of this
result for a model independent extraction of the mixing angle $V_{ub}$ are
explored.
