Therefore be it
Resolved by the Senate and House of Representatives of the United States of America in Congress assembled, That the state of war between the United States and the Imperial Government of Japan which has thus been thrust upon the United States is hereby formally declared; and the President is hereby authorized and directed to employ the entire naval and military forces of the United States and the resources of the Government to carry on war against the imperial Government of Japan; and, to bring the conflict to a successful termination, all of the resources of the country are hereby pledged by the Congress of the United States.
Approved, December 8, 1941, 4:10 p.m., E. S. T. For those neocons that haven't seen one, this is a formal declaration of war.
You're saying that in order for Congress to be declaring war, it has to use the exact same words of past declarations? ...or some anarcho-leftist magic words? In my humble non-lawyer opinion, the following said it clearly enough.
