For most Americans, “war” conjures images of Pearl Harbor or 9/11—clear-cut moments that trigger a formal declaration from Congress. But that hasn’t been the reality for over 75 years. Instead, the U.S. has perfected a different playbook: fighting US undeclared wars across the globe—from Iraq and Iran to the escalating tensions with Venezuela—all without ever officially declaring hostilities.

The Forgotten Rule: What the Constitution Actually Says
Article I, Section 8 of the U.S. Constitution is crystal clear: only Congress has the power to declare war. Yet, the last time this happened was in 1942, against Bulgaria, Hungary, and Romania during World War II. Since then, every major U.S. military engagement—from Korea and Vietnam to Afghanistan and Iraq—has occurred without a formal declaration .
This isn’t an oversight; it’s a deliberate shift in power from the legislative to the executive branch, enabled by evolving interpretations of “national security” and “commander-in-chief” authority.
US Undeclared Wars: A Brief (But Bloody) History
The scale of American military action since 1945 is staggering. One analysis estimates the U.S. has launched over 200 military interventions since the end of World War II . Another source claims involvement in as many as 96 countries through invasions or interventions . These range from full-scale invasions (like Iraq in 2003) to drone strikes, covert ops, and naval blockades.
Notable examples include:
- Korea (1950–1953): Called a “police action,” not a war.
- Vietnam (1955–1975): Authorized via the Gulf of Tonkin Resolution, not a declaration.
- Grenada (1983) and Panama (1989): Short invasions justified under “restoring democracy” and “protecting citizens.”
- Kosovo (1999): A 78-day NATO bombing campaign led by the U.S.—again, no declaration .
The War Powers Resolution: A Toothless Tiger?
In 1973, Congress tried to claw back control with the War Powers Resolution (P.L. 93-148), passed over President Nixon’s veto . The law requires the president to notify Congress within 48 hours of deploying troops and limits military engagement to 60 days (plus a 30-day withdrawal period) without congressional authorization .
But here’s the catch: every president since Nixon has ignored or circumvented it. They argue it infringes on their constitutional role as commander-in-chief. Congress, meanwhile, rarely enforces it—often because members fear being labeled “weak on defense.” The result? A legal fiction that allows endless military action without accountability .
Modern Shadow Wars: Iraq, Iran, and Venezuela
Today’s US undeclared wars are more subtle—but no less destructive.
Iraq remains the starkest example. The 2003 invasion was justified not by a war declaration but by a joint resolution citing WMDs (which were never found) . Over 4,400 U.S. soldiers and hundreds of thousands of Iraqis died in a conflict that reshaped the Middle East.
Iran has never been formally invaded, yet the U.S. wages a multi-pronged campaign: cyberattacks (like Stuxnet), targeted assassinations (e.g., Qasem Soleimani in 2020), and crippling sanctions—all acts of war by any other name .
Now, Venezuela is in the crosshairs. Reports indicate the U.S. is already conducting a “hidden war” using drones, naval pressure, and economic strangulation—ostensibly for counter-narcotics, but clearly aimed at regime change . In 2025 alone, the U.S. reportedly bombed at least seven countries, including Venezuela, Syria, and Somalia .
Why Does It Matter?
Bypassing a war declaration isn’t just a legal technicality—it has real consequences:
- Accountability evaporates: Without a formal vote, Congress avoids responsibility for failed wars.
- Public scrutiny fades: “Military operations” sound less urgent than “war,” reducing media and voter attention.
- Endless conflict becomes normalized: The U.S. has been at war for over 90% of its existence since 1776—and 60% of those interventions occurred after 1950 .
Conclusion: The Cost of Convenience
The pattern is undeniable: the U.S. uses US undeclared wars as a tool of first resort, not last. From Baghdad to Caracas, this strategy offers speed and secrecy—but at the cost of democratic oversight, international law, and human lives. As tensions rise with global rivals, understanding this hidden machinery of American power isn’t just academic—it’s essential for anyone who believes in peace, transparency, and constitutional governance.
