I've seen the whole conversation ad read the whole transcript.
Four Americans butchered is a tragedy, a travesty, an abso-*******-lute outrage...."Not optimal" is technocratic bean counter speak....Obuttfuck is a cold callous dickhead.
*sigh*
He wasn't referring to the deaths.
The question was whether the communications between the agencies was optimal or not.
He said that the deaths showed that it (communications) clearly wasn't optimal.
Pretty clear when you see the whole exchange, but easy to chop up and take out of context if you've a mind to.
