Going to war against Iran would be no minor matter, and President Trump is irresponsible to act in such a flippant manner. Attacking Iran could trigger a prolonged, costly nightmare in both treasure and blood. Rep. Tulsi Gabbard (D‑HI), a Democratic presidential candidate, likely is prophetic that a war against Iran would make the Iraq War look like a cakewalk. Tehran certainly has a multitude of ways to retaliate for U.S. aggression and to escalate the bilateral confrontation. U.S. leaders would be wise not to venture farther down that perilous path.
