The Shifting Overton’s Window in International Affairs
How President Trump redefined international “norms” under his recent foreign policies in Venezuela and Greenland.
Redefining the Boundaries of Acceptable State Behaviour
The global political landscape this year has witnessed a dramatic shift of what state behaviour is considered acceptable in international affairs. One method of assessing this change is through the lens of the Overton Window, defined as the range of policies considered acceptable by the majority of a population at a particular time (Britannica, 2026). Under the presidency of Donald J. Trump, actions such as the extralegal capture of Venezuela’s President Nicolás Maduro and an assertive, coercive effort to acquire Greenland have expanded the spectrum of plausible foreign policy options, normalising approaches that are arguably seen as incompatible with international law or even imperialistic in nature.
When applying the Overton Window to international policy, it traditionally constrains states to operate within established norms of sovereignty, territorial integrity, and the non-use of force. For much of the postwar period, these principles underpinned the liberal international order, reinforced through international law and institutions. Trump’s approach has challenged these directly, not through gradual change, but through highly visible, norm-breaking actions that redefine what can be publicly defended as legitimate statecraft.
The Capture of Maduro and the Normalisation of Extralegal Force
On January 3, 2026, US forces conducted an operation in Caracas that captured and forcibly removed Venezuelan President Nicolás Maduro and his wife, Cilia Flores. President Trump framed the operation as a counter-narcotics and national security action, arguing that Maduro posed a direct threat to American interests. However, analysis saw the intervention as a violation of Venezuelan sovereignty and international law, lacking justification under the UN Charter’s provisions for self-defence or collective security (Chatham House, 2026).
What makes the operation significant from an Overton Window perspective is not only the act itself, but the manner it was justified. Trump’s assertion that the United States would “run [Venezuela] until such time as we can do a safe, proper and judicious transition” (CBS News, 2026) marked a return to interventionist language that had previously been considered outside the bounds of acceptable discourse. The administration didn’t apologise for the takeover, rather treating it as a straightforward display of power, showing that direct US control of foreign territory has crept back into the Overton Window of its international affairs.
Greenland and the Revival of Territorial Ambition
Alongside the Venezuela operation, the administration accelerated its efforts to bring Greenland under US control. What began as a dismissed suggestion during Trump’s first term evolved into a sustained campaign of coercive diplomacy targeting Denmark and the European Union. By citing the necessity of Greenland’s rare-earth minerals and strategic Arctic positioning, Trump framed territorial acquisition as a pragmatic national security requirement. While the administration eventually walked back the most extreme threats of military action and trade embargoes following intense diplomatic pushback, the ‘climb down’ did little to restore the previous status quo. By forcing the world to treat the purchase of a sovereign territory as a serious proposal, Trump successfully shifted the Overton Window. Even without a formal acquisition, he established a precedent where the violation of territorial integrity is no longer a forbidden topic, but a leverage point in modern statecraft.
Global Instability and Shifting Standards
These actions have strained global alliances and weakened the rules that govern how countries behave. European allies are alarmed by the moves in Venezuela and Greenland, seeing them as dangerous examples that break international law. At the United Nations, many countries labelled the capture of Maduro as illegal, whilst Russia and China have used these events to claim that the US only respects a country’s independence when it is convenient for them to do so.
By pushing the boundaries of what is considered ‘acceptable’ policy, the Trump administration has created a ripple effect. Internationally, other countries may now feel emboldened to use force, believing the old rules no longer apply. At home, these actions have sparked a fierce debate over whether the President has overstepped his constitutional power. While critics warn that using force without legal backing destroys democratic accountability, supporters argue this is simply ‘realism’ in a competitive world. The core danger is that once these international rules are broken, it is incredibly difficult to put them back in place.
Conclusion: A New Baseline for International Conduct
Trump’s recent foreign policy moves represent a fundamental change in how countries are expected to act. By openly supporting the takeover of governments and the pressure to seize land, the administration has pushed the Overton Window into once-forbidden territory. These actions are not just one-off events; they have created a new, more aggressive baseline for international conduct. The danger of this shift is that it’s cumulative. Each time a global rule is broken, it lowers the reputational cost for the next act, making it easier for leaders to choose force over diplomacy. As these tactics become normal, the line between an emergency measure and standard policy begins to disappear.
Canadian Prime Minister Mark Carney best captured this new reality during his January 2026 speech at Davos. Reflecting on the collapse of long-standing rules, Carney warned that “we are in the midst of a rupture, not a transition…The old order is not coming back…Call it what it is: a system of intensifying great-power rivalry where the most powerful pursue their interests using economic integration as coercion.” (WEF, 2026)
Ultimately, whether this leads to a new way of working with allies or sparks long-term global chaos depends on how other nations and future US leaders respond. If middle powers and allies do not find a way to act together, they risk being sidelined in a world where, as Carney put it, “if you’re not at the table, you’re on the menu.” (Ibid, WEF)
