Joint Chiefs Chairman Gen. Dan Caine has been advising President Trump and top officials that a military campaign against Iran could carry significant risks, in particular the possibility of becoming entangled in a prolonged conflict, according to two sources with knowledge of those internal discussions.

Why it matters: There’s an ongoing debate at the top levels of the Trump administration about how to handle the Iran standoff and what the consequences of each option would be. At the moment, several of the voices in Trump’s circle are urging caution, though some sources think Trump himself is leaning towards a strike.
