Trump's Muddled Military Messaging

The Trump administration’s miscommunication about the whereabouts of a naval strike force that includes the aircraft carrier Carl Vinson underscores the emptiness of the administration’s tough-sounding but vague rhetoric about putting states “on notice” and ending eras of “patience”.  The episode with the Vinson—which was sailing south for an exercise with the Australians as the administration was suggesting publicly that it was sailing north toward Korea—will lead additional foreign observers to conclude that the muscular talk is just talk.  This is on top of what was already a severe international credibility problem with a president who has established a well-deserved reputation for dishonesty.

All of this is bad enough, but it obscures further problems entailed in Trump’s use of military force to send messages to foreign regimes.  This form of messaging, as illustrated by the cruise missile strike in Syria, plays so much to Trump’s inclinations that we are likely to see many more instances of it.  It is an emphatic and dramatic gesture that may be grounded, as the strike in Syria evidently was, more in emotion than in any careful thought about long-term strategy.  Sort of like a tweet with lots of exclamation points.  Following the embarrassment involving the Vinson, Trump’s advisers may lean more than before toward favoring actual use of force, lest the empty rhetoric seem even more empty.  But as long as either the advisers or the president himself are disinclined to become deeply committed in any one situation, most of the use of force will be rationalized as the sending of “messages”.

Probably the message from the strike in Syria that the White House valued most was one sent to domestic audiences.  The missile strike won support across a wide part of the American political spectrum.  The action could be presented as a break from Obama, amid a plethora of international problems that the current administration has no better ideas or options for solving than Obama did.  The missile strike was especially cheered by neoconservatives who see any use of military force against a disliked regime as one more step toward neocon recapture of control over U.S. foreign policy.  But as for sending messages to foreigners and foreign states, there is no indication that the Trump White House fully understands the principles involved in making that kind of messaging effective—principles that the strategist Thomas Schelling explained half a century ago.

There is, first of all, the question of what exactly is the message.  Bombs and missiles are not articulate things; they are incapable of explaining objectives, limits, red lines, or anything else that the users of them may want to communicate.  Trump’s cascade of flip-flops, and the vague nature of the rhetoric about putting people on notice and running out of patience, do not help in the communication. 

The best face-value interpretation of the attack in Syria is that it had to do with punishing and deterring use of chemical weapons.  But if the purpose was to enforce an international norm and international law about use of chemical weapons, persuading anyone of that was made more difficult by the lack of any effort to obtain international sanction, especially through the United Nations Security Council, before a retaliatory strike.  Moreover, other bellicose administration rhetoric about Syria has sounded much broader.  And indeed, casualties from chemical weapons have been a tiny fraction of overall casualties—including civilian suffering inflicted by the regime’s military operations—in the Syrian war.  So if it really was just about chemicals, how much good did any message-sending strike do?  The Syrian regime evidently was not deterred from  promptly attacking again the same neighborhood that was the scene of the chemical incident.

Messages—like names, and unlike sticks and stones—don’t necessarily hurt very much.  A message-sending military attack can actually help the regime or group that is targeted, by giving it an opportunity to demonstrate to its constituencies how it is surviving the attacks of, standing up to, and striking back against the American superpower.  And it does so with the added benefit of riding any popular resentment against foreign, especially U.S., intervention and resentment against any casualties inflicted by foreign military operations.

A key, per Schelling, to making a message-sending action effective is to link it in the minds of the targeted regime to the prospect of more destructive action if certain demands or standards are not met.  One way of achieving such linkage is for the message-sending operation to carry, by its very nature, the risk of escalation into something bigger and more destructive.  The missile strike in Syria did involve a danger of escalation, especially if it had killed any Russians, but there is no indication that the Trump administration wants a military clash with Russia (although the administration’s current posture toward Russia is yet another topic infected by muddled messaging).
