John is joined by former C.I.A. and Pentagon chief of staff Jeremy Bash to discuss the decision facing Donald Trump about going to war with Iran. Bash explains the history of the Iranian nuclear program and where it likely stands today; what Israel’s dramatic new efforts to destroy it have and haven’t achieved; the intelligence, domestic political debate, and other factors Trump is weighing as he considers intervening; and the best and worst case scenarios if he does. Jeremy also offers view of the sidelining of Tulsi Gabbard after her bizarre bid to sway Trump by means of a slickly produced social media video.
