• US rarely declares war, relying on military actions instead
• Presidents often bypass Congress for military operations
• Iran strikes continue decades-long trend of covert conflicts

When the United States bombs another country, deploys troops or launches a sustained military campaign, most people instinctively call it a war. But legally, the word “war” almost never appears anymore in official US decisions.

The current conflict involving US strikes on Iran highlights this gap between reality and terminology. American and Israeli forces have attacked Iranian targets and killed senior leaders, yet the US government has not asked Congress to declare war.

That may sound unusual, but it has been the pattern for decades, CNN reported.

When the United States actually declared war

Earlier generations handled war very differently. Presidents formally asked Congress to declare it.

In April 1917, President Woodrow Wilson went before Congress to request a declaration of war against Germany during World War I. He argued that Germany’s submarine warfare and the intercepted Zimmermann Telegram, which proposed a German alliance with Mexico against the US, left the country with little choice.

Congress voted in favour.

The same process unfolded during World War II. After Japan attacked Pearl Harbor in December 1941, President Franklin Roosevelt addressed Congress the next day and asked lawmakers to declare war. Congress approved the request within hours.

Those votes left no ambiguity. The United States was officially at war.

How the pattern began to change

The shift began after World War II. The Korean War was the first major conflict where the US fought without a declaration of war.

President Harry Truman sent American forces to fight in Korea but described the operation as a “police action” under the authority of the United Nations. Congress funded the war effort but never formally declared war.

Vietnam followed a similar path. In 1964 Congress passed the Gulf of Tonkin resolution after reports that North Vietnamese forces had attacked US ships. The resolution allowed President Lyndon Johnson to expand military operations without

issuing a formal declaration of war.

Years later, it emerged that the attacks had not occurred in the way officials initially described.

Congress tries to take back control

The experience of Vietnam triggered a backlash in Congress. Lawmakers worried that presidents had gained too much freedom to send the country into war.

In 1973 Congress passed the War Powers Resolution. The law requires the president to notify Congress when US forces are introduced into hostilities and sets a 60-day limit for military action unless Congress authorizes it.

In theory, the measure was meant to restore Congress’s role in decisions about war.

In practice, presidents have often treated the requirement as a formality rather than a restriction.

Modern wars without the word “war”

Since the attacks of September 11, 2001, US military operations have been justified under broad authorizations to fight terrorism. Those authorisations have been used for military actions in multiple countries.

Presidents have also relied on the argument that, as commander in chief, they can launch limited military operations without asking Congress for permission.

That is why many conflicts are described using phrases such as “military action,” “operations” or “collective self defence” rather than war.

The result today

The conflict involving Iran fits neatly into this pattern. The administration notified Congress through a required report about the military action but did not request a declaration of war or a specific authorisation to use force.

Some lawmakers have called for a vote on the issue. But congressional leadership has shown little appetite for forcing that debate.

As a result, the United States finds itself in a situation that has become familiar over the past seventy years. The country fights wars that are rarely declared and sometimes not even officially called wars at all.
