late today, nbc news reported that according to three sources, u.s. intel indicates that the drone attacks on the oil facilities originated from iran which still begs the question of why it would be a u.s. fight. here with us tonight to talk about it, general barry mccaffrey, retired u.s. army four star. heavily decorated combat veteran of vietnam. and importantly, a u.s. ground commander in the gulf war. he has been to this oil field in saudi arabia. also with us tonight, jeremy bash, former chief of staff at the cia and at the pentagon. general, i'd like to begin with you. tell us about this facility and tell us your view of the optics of this president saying we are locked and loaded and seemingly awaiting instructions from the kingdom. >> look, it was a very serious blow at saudi arabia. it probably knocked half their total production offline. some of it maybe for months.
