Obama “Now with respect to Libya, as I indicated in the last debate, when we received that phone call, I immediately made sure that, number one, that we did everything we could to secure those Americans who were still in harm’s way;”
“that we did everything we could to secure those Americans who were still in harm’s way”
“everything we could” Exactly my point, CIA operators were all that we could do, given the unshaped and rapidly evolving battlefield there.
We have a number of rapid response units worldwide, some are more quickly deployed than others, largely depending on air assets for deployment, ground support, and overwatch.
We had three units deployed that were tactically capable of relieving the Benghazi mission. However, two were committed to relief of the embassies in Cairo and Khartoum and the third committed to AfPak.
We were stretched too thin. Africom wanted to send the unit staged for Khartoum but was denied, hence General Ham’s disagreements.
