Get a good nights sleep, be well prepared and relaxed. If BHO attacks defend, then fire off a salvo at him. BHO does not like to be ridiculed. Ridicule him, laugh at him gently of course, and make him look the fool and he will begin to unfold.
Ask him why he did not attend hardly any intelligence briefings? Then ask does he regret not having attended them? Could he have prevented the massacre had he put in place better security measures. Are these countries really your friends? Why didn't they nip this in the bud? Then ask him did he fail to pay off his allies and they were getting back at him?
If possible sneak in this question, why did you give China and Finland our stimulus money?
