Conclusion
Throughout U.S. history, formal declarations of war have been rare, with Congress exercising its constitutional authority to declare war only 11 times. This process, requiring explicit legislative approval, contrasts with modern military authorizations, such as the War Powers Resolution of 1973, which allows the President to engage in military actions without a formal declaration. These shifts have significantly influenced U.S. foreign policy and the balance of power between the legislative and executive branches (history.com).
