Trump gets caught in a dilemma over a Saudi plea for military help

For two weeks, the question of whether to yield to pleas from Saudi Arabia and order the U.S. military to strike targets in Yemen controlled by the Iran-backed Houthis has bedeviled President Donald Trump. A decision to go forward could open another front in the war against Iran that Trump started but has been unable to end as it spreads economic shock around the globe. The president had wavered for weeks over the Saudi appeals for help in fighting the Houthis, who took advantage of the instability in the Middle East and reignited their war with the kingdom this summer.
