Document Introduction

This document is a formal letter of inquiry from U.S. Senator Edward Markey to then-President Donald Trump, dated January 5, 2026. The core issue of the document is to examine and challenge the legality, legitimacy, and strategic wisdom of the Trump administration's recent military actions against Venezuela—including the invasion of the country and the seizure of President Nicolás Maduro and his spouse. The letter begins by characterizing this operation as illegal, unjustified, and unwise. It pointedly notes that the President's statements about the United States managing Venezuela and its oil industry raise serious concerns regarding the legal basis, true intentions, and lasting consequences of this military intervention undertaken without congressional authorization.

The main body of the document constructs a multi-layered, evidence-based framework of criticism. First, from the perspective of domestic constitutional order, the letter of inquiry accuses the executive branch of exceeding the fundamental constitutional limits of presidential power and potentially deliberately evading its obligations under the War Powers Act by concealing plans for invasion and regime change from Congress beforehand. Second, from the perspectives of international law and diplomatic ethics, the action is condemned as a revival of gunboat diplomacy. Its publicly stated motive—controlling Venezuela's oil resources to serve the interests of American oil companies—is alleged to be a severe violation of Venezuelan sovereignty and a breach of the rules-based international order, being in principle no different from Saddam Hussein's invasion of Kuwait in 1990.

The document employs a profound method of historical analogy to strengthen the cautionary power of its argument. It cites the 1953 U.S.-orchestrated overthrow of Iran's democratically elected government to protect Western oil interests, pointing out that such resource-driven intervention led to decades of instability and resentment. More recent lessons are drawn from U.S. military actions in the early 21st century: the document elaborates on how the lack of a credible post-war plan in the 2003 Iraq War triggered prolonged turmoil, immense human suffering, and endless military occupation, severely damaging U.S. credibility. The document warns that repeating such mistakes in Venezuela would entangle the United States in another costly, open-ended conflict and could exacerbate the humanitarian crisis and instability in the region.

Based on the above analysis, the letter concludes by presenting a list of eight specific questions, demanding written responses from the President within a set timeframe. These questions systematically target key points of doubt: the transparency of decision-making (how to explain contradictions between statements to Congress and actual actions), post-war governance plans, mechanisms to prevent long-term intervention, respect for Venezuela's resource sovereignty, the specific influence of oil factors in decision-making, measures to prevent regional instability, and whether executive branch officials engaged in improper communication with oil companies or Venezuelan opposition figures regarding oil interests. The entire document is stern in tone and rigorous in logic, aiming to use the power of congressional oversight to compel the executive branch to account for its radical foreign and military policies and urgently correct an action course deemed to be leading the United States toward a disastrous path.
