Militarisation at Home: Trump’s National Guard Deployment to Chicago and Its Political Reverberations

The Trump administration’s militarisation of law and order seems to many a necessary response to social deterioration, but does it lead to the backsliding of American democratic values? 

Trump, Crime, and Political Unrest

US President Donald Trump has announced plans to deploy the National Guard to Chicago, citing the imperative to restore law and order. He claimed that “Chicago is a mess” and that local supporters had been “screaming for us to come”, despite crime, including homicides, declining in the last year (Reuters, 2025c), as shown in figure 1 using data from the Council on Criminal Justice (2025). This decision follows prior deployments to Washington, D.C. and Los Angeles (Reuters, 2025a), suggesting an emerging pattern of militarised responses to domestic, political and social unrest.

The announcement has provoked widespread criticism from political adversaries, scholars, and international observers. Critics contend that the move signals an authoritarian shift in American governance, with much of the criticism coming out of Illinois. Illinois Attorney General Kwame Raoul condemned the action as “turning the military on American citizens,” further describing it as “un-American” (The Guardian, 2025). Similarly, Lieutenant Governor Juliana Stratton has accused the president of engaging in “political theatrics” (The Guardian, 2025).

Epitomising the outrage, Chicago Mayor Brandon Johnson rejected Trump’s assertion that the city faces an emergency requiring federal intervention, stating that “There are many things the federal government could do to help us reduce crime and violence in Chicago, but sending in the military is not one of them” (Reuters, 2025c).

Constitutional and Civil–Military Tensions

The deployment raises constitutional questions regarding the separation of powers and the balance between federal and state authority. Traditionally, National Guard deployment within a state requires either the governor’s request or extraordinary federal intervention under the Insurrection Act (Brennan Center for Justice, 2025). Illinois Governor J.B. Pritzker said his state had made no request for federal intervention and the Illinois attorney general said legal action would be taken to prevent a federal deployment in Chicago (Reuters, 2025b).

Furthermore, the politicisation of the military poses risks to the long-standing American norm of civilian control and nonpartisan military service, as deploying troops in politically contested contexts threatens to blur the boundary between domestic law enforcement and military force. However, such erosion of civil–military boundaries has been a recurring concern in US history (Council on Foreign Relations, 2025).

Domestic Political Fallout

Domestically, the Chicago deployment has deepened polarisation. Supporters of the president frame it as a necessary assertion of authority, and White House spokesperson Abigail Jackson even accused the Democrats of “doing publicity stunts” in response to their uproar (Politico, 2025). On the contrary, House Minority Leader Hakeem Jeffries accused Trump of “manufacturing a crisis”, to justify sending federalised national guard troops into Chicago (The Guardian, 2025).

Additionally, civil society groups have warned of potential human rights violations should the military engage in crowd control or policing functions. For example, the American Civil Liberties Union of Illinois stated that “this step will only make people across our city and the area feel less safe and less secure” and “where we see violations of basic rights, we will act and demand that Trump and his federal forces are held accountable for these violations” (American Civil Liberties Union of Illinois, 2025).

The move also intersects with electoral politics. With the 2026 midterm elections looming, Trump’s administration will be aware of the mobilising power of crime narratives among swing voters. By emphasising images of troops patrolling city streets, the administration will seek to reinforce its brand of toughness, contrasting it with Democratic leaders whom it depicts as ineffective. However, this strategy could also risk alienating more moderate voters who are wary of creeping authoritarianism and concerned about the use of military force against citizens.

International Perceptions and US Global Leadership

Beyond domestic politics, the deployment has global implications. For decades, the United States has positioned itself as a champion of liberal democracy and civilian governance worldwide. Washington has often criticised other states for employing militarised tactics against domestic opponents or bypassing subnational authority in pursuit of centralised control, as shown with Hong Kong earlier this year (AP News, 2025). By deploying troops in defiance of local officials’ objections, the US risks eroding its credibility as an advocate of federalism, civil rights, and democratic checks and balances.

International observers are also understandably watching closely. For example, allies in Europe, already unsettled by Trump’s transactional approach to NATO and his disputes with the European Union, may interpret the Chicago deployment as further evidence of democratic backsliding.

Meanwhile, authoritarian rivals such as Russia and China could exploit the episode rhetorically, pointing to it as proof of American hypocrisy. In the context of a global competition between democratic and authoritarian models of governance, such incidents weaken the moral authority of US foreign policy.

Comparative Perspectives: Militarisation in Democracies

The deployment also invites comparative analysis. Several democracies, including Brazil, South Africa, and India, have historically employed military forces to address internal security challenges (Ricardo, 2022; Institute for Security Studies, 2012; Indian Defence Review, 2012). A critical concern, however, is that once military involvement in domestic affairs becomes normalised, it often proves difficult to reverse. In Brazil, for example, the recurrent use of military units in favela operations has undermined the capacity of civilian police forces and has increasingly blurred the lines between policing and warfare (Harvard International Review, 2020).

The United States now faces a parallel risk. If urban crime and social unrest are persistently framed as threats to national security rather than issues of local governance, federal military intervention may gradually become an accepted precedent.

The deployment of the National Guard to Chicago transcends a localised dispute over crime and public safety, it reflects deeper structural tensions within American democracy. This action underscores the ongoing contest between federal and state authority, the increasing propensity to invoke military force in civilian governance, and the broader risks of democratic backsliding under populist leadership. Domestically, such measures exacerbate political polarisation, galvanise Trump’s base, and risk alienating centrist constituencies. On the international stage, they compromise the United States’ credibility as a defender of liberal democracy and provide ammunition to authoritarian critics.
