Donald Trump campaigned on keeping America out of endless foreign conflicts. But as the war between Israel and Iran escalates, the president finds himself in a geopolitical bind that could override his “America First” doctrine.

The U.S. has unique power to force restraint, but with the offensive on its third day and the death toll rising, there is little sign Trump will wield his leverage.
