How do you define war, law homework help

How do you define “war?” What are your thoughts on whether the “War on Terror” is really a war as contemplated by the U.S. Constitution?
Should the war powers be given to the President, which were addressed in Unit One Lecture notes, in the “War on Terror?”
Discuss your response, whether affirmative or negative, with respect to whether this will set a good or bad precedent for future “wars” in which we are in essence fighting an idea without Congressional deliberation and approval.
