The last time Congress declared war was on December 11, 1941, against Germany in response to its formal declaration of war against the United States. This was accomplished with wording that took less than one-third of a page, without any nitpicking arguments over precise language, yet it was a clear declaration of who the enemy was and what had to be done. And in three-and-a-half years, this was accomplished. A similar resolve came from the declaration of war against Japan three days earlier. Likewise, a clear-cut victory was achieved against Japan. Many Americans have been forced into war since that time on numerous occasions, with no congressional declaration of war and with essentially no victories. Today’s world political condition is as chaotic as ever. We’re still in Korea and we’re still fighting the Persian Gulf War that started in 1990. The process by which we’ve entered wars over the past 57 years, and the inconclusive results of each war since that time, are obviously related to Congress’ abdication of its responsibility regarding war, given to it by Article I Section 8 of the Constitution. Congress has either ignored its responsibility entirely over these years, or transferred the war power to the executive branch by a near majority vote of its Members, without consideration of it by the states as an amendment required by the Constitution.

Please don't cut and paste that long nonsequitur.
Short and to the point. Congress authorized the use of force against a defined enemy.
Congress declared war.
