Los Angeles is burning. Earlier this year, seasonal fires ripped through the Southern California city, but now, the fires are entirely manmade. In response to the Trump administration’s deportation policy, left-wing activists and opportunistic rioters have taken to the streets to vandalize property, incinerate automobiles, and assault law enforcement officers. The images emerging from the city are shocking: thugs hurling rocks from an overpass onto police; men spinning motorcycles around burning debris; a masked, shirtless rioter waving a Mexican flag atop a burned-out autonomous car.

In short, the Left is giving President Trump all the visual symbolism he needs to advance his immigration agenda. Most Americans see chaos in the name of a foreign flag and find it repellent. Though Trump’s language about a migrant “invasion” has sometimes been dismissed as hyperbolic, it seems that the Left is intent on turning it into a material reality.

The question: How should the president respond? Many on the right may feel an instinctual reaction to “send in the troops.” While this concern for law and order is natural and merited, it must be pursued in a way that maximizes the chance for success and minimizes the chance for blowback. As the president considers his options, he might keep in mind a number of strategic points that, if implemented, will increase his leverage in the fight for large-scale deportations.

The administration must deny the Left a strong visual counterargument. It’s easy to see how scenes of militarization, abuse of demonstrators, or a violent death could reverse public sympathies and present the administration as abusing its authority. The language of politics is visual—and therefore emotional, which means that a single mistake can reverse the flow of opinion and imperil the president’s immigration agenda. Left-wing tacticians have trained their foot soldiers to bait law enforcement into confrontation and to play victim for the press, to great effect.

To prevent this scenario, Trump has a number of strategic options available to him. First, rather than sending in more troops to stop the fires, the president might be better advised to hold off. Right now, California governor Gavin Newsom has sided with the demonstrators, but if the riots spread further, this stance will cost him in public opinion, and eventually, he will have to assume the mantle of authority. The public will expect Newsom to restore order, and he’ll have to incur the risk of using force.
