President Trump has said it would be "foolish" to cancel billions of dollars in weapons deals with Saudi Arabia over the kingdom's involvement in the disappearance of journalist Jamal Khashoggi — a remarkably blunt admission of the role the international arms trade plays in U.S. foreign policy.
The big picture: The U.S. is the world's top arms exporter, competing directly with Russia and increasingly China in a global market that's worth upwards of $89 billion annually. Saudi Arabia is currently the No. 1 buyer of U.S. weapons, purchasing nearly three times as much as any other country over the past two years. Arms deals tie ethics to economics, and they can exacerbate geopolitical tensions in high-risk areas like Yemen and North Korea.
