Which brings to the fore the largest problem: the Trump administration’s national-security team. There is no such thing as a Platonic ideal of strategy. There is, rather, only strategy as can be executed by a particular group of people at any time. Any war—and if you are in the business of blowing people up, you are at war—involves improvisation and reaction. As Winston Churchill somberly observed, “Always remember, however sure you are that you can easily win, that there would not be a war if the other man did not think he also had a chance.” Iran cannot beat the United States in the field, but it can win the war politically, and may very well do so.
The dominant tone in the American government is military assertiveness. The American military has in its theater commander, General Frank Mackenzie Jr., and its chairman of the Joint Chiefs of Staff, General Mark Milley, two tough, experienced, aggressive commanders, with lots of time downrange in Iraq, where they personally felt the sting of Soleimani’s tactics. Secretary of State Mike Pompeo is forward-leaning, while Defense Secretary Mark Esper, promoted unexpectedly from being secretary of the Army, has been a capable organizer but has not articulated a distinctive strategic point of view. Neither has the national-security adviser, Robert O’Brien. None has shown a substantial inclination to buck the president’s wishes or even his inclinations.
