Clause 1
Military Actions Without Declarations Of War
Throughout the history of the U.S.A. under the Federal Constitution, there have been hundreds of instances in which the nation's Armed Forces, operating solely on the basis of presidential orders and without the benefit of congressional declarations of war, were engaged in military conflict abroad. While most of these undeclared conflicts were short rather than protracted engagements, each beginning and ending so quickly that there was no opportunity for congressional consideration and approval of the President's action, Congress has not always declared war when the nation became involved in a longer, more drawn out conflict. In fact, Congress has declared war in only five of the thirteen major shooting wars in which the U.S.A. has been involved:
The War of 1812 against Great Britain [1812-1814]*;
The Mexican-U.S.A. War [1846-1848]*;
The Spanish-American War [1898]*;
World War I [1917-1918]*;
World War II [1941-1945]*.
In each of the eight other major wars involving the U.S.A., Congress did not pass a declaration of war and the President did not recommend to Congress that it pass such a declaration. The eight undeclared major wars were:
The U.S. naval war with France [1798-1800]*;
The first war against the Barbary pirate states of
North Africa [1801-1805]*;
The second war against the Barbary states [1815]*;
The Mexican-U.S.A. conflicts immediately preceeding
American entrance into World War I [1914-1917]*;
The Korean War [1950-1953]*;
The Vietnam War [1961-1975]*;
The Persian Gulf War [1991]*;
The Kosovo-Yugoslav War [1999]*.
