In recent weeks, Iranian ships have harassed a number of American vessels in the crowded waters of the Persian Gulf. Republican presidential nominee Donald Trump has responded that if such actions continued under his presidency, Iranian ships would be “shot out of the water.”
Such an approach would send a strong signal, but would also likely turn a minor incident into a significant international crisis, causing oil prices to skyrocket and potentially embroiling America in another major conflict in the Middle East. Fortunately, the United States has a number of options at its disposal that do not come with this type of risk, and that have proven in the past to be effective in deterring provocative Iranian behavior.
