I do not think the 32 people were sent to Benghazi to be killed. I think the "why" is that obama/clinton found themselves in a circumstance which required, in their minds, a decision. Remember the obama narative was...'Osama had been killed'...al Quaeda is on the run...(election declarations)...Suddenly, al Quaeda assaults the embassy (al Quaeda is alive and well..this contradicts the obama political narrative)...if found out obama looks like the idiot he is 7 weeks prior to the election.
OPTIONS: 1. Do everything he can do to save the personel at the consulate. 2. Allow the 32 people at the consulate be killed by the attackers and continue with the political ruse.
Obama/Clinton chose the second choice.
IMHO, Clinton scrubbed John Does with probable islamic ties from OK City bombing and then sanitized the fate of Flight 800 for the same reason (as well as blaming OK CIty on 'Right-Winged Extremists" which took most of the heat off the ATF for Waco).
Even the WTC bombing was downplayed, and later that led to a big event which was undeniable--9/11
If Clinton, et. al. had admitted there was a 'problem', it would have necessitated a response the administration was ill equipped to deliver and damaged the kumbaya fable that all was well with the world (at least until he had to wag the dog).
