We are told Petraeus' alleged mistress perceived Kelley as a threat and sent disturbing emails to Kelley who then contacted a "friend" at the FBI, and the next thing we know, prominent military leaders are dropping like dominoes.

All this drama reminds me of a historical event that took place in 1941 when Joseph Stalin purged the Soviet Union's Red Army of its best officers and leaders because he feared a military coup due to growing opposition to his highly unpopular policies.

Hopefully, in our case, it's a bit less nefarious; Obama is sitting idle while the Benghazi scandal makes its way through the ranks and does nothing to slow it down.
