It depends on what the meaning of "war" is; along with the meaning of every other word I've ever used in my life.
JOINT RESOLUTION Declaring that a state of war exists between the Imperial Government of Japan and the Government and the people of the United States and making provisions to prosecute the same.
Whereas the Imperial Government of Japan has committed unprovoked acts of war against the Government and the people of the United States of America: 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.
A grade school kid could understand it's meaning. Compare it to this Joint Resolution to Authorize the Use of United States Armed Forces Against Iraq If you try to read it you'll just get mad. It was written by lawyers for loop holes. No one required to make a solid commitment to it. She likely laughed and whispered you fools under her breath when she signed the stinking thing. If our troops are to be sent into combat they deserve no less than a full declaration of war. Congress did not make such a declaration and Hillary is using it against the GOP for her gain.
