According to The Wall Street Journal, Trump is considering military action against Iran’s nuclear facilities:
President-elect Donald Trump is weighing options for stopping Iran from being able to build a nuclear weapon, including the possibility of preventive airstrikes, a move that would break with the longstanding policy of containing Tehran with diplomacy and sanctions.
The surest way to convince the Iranian government to build nuclear weapons is to attack their nuclear facilities. In addition to being reckless and wrong, “preventive” military action would practically guarantee the outcome that hawks say they want to prevent. The only thing stupider than using force to eliminate a non-existent threat is using force to create a threat that wouldn’t have existed otherwise.
