Matthew Dowd, a former adviser to President George W. Bush, is quite correct to call attention to whether the United States of America has gone to war under the rules set forth by the U.S. Constitution.

He was speaking this morning on ABC-TV’s “This Week” and said the debate should have commenced 30 years ago.

The Constitution states in Article I, Section 8 that Congress has the power “To declare war.”

There it is. No argument. No qualifier. The power to declare war rests exclusively with Congress.

And yet …

We’ve been to war in Iraq, Kuwait, Bosnia, Panama, Grenada, Vietnam, Korea — am I missing anything? — without Congress voting on a declaration of war.

The discussion this morning comes just as the United States is gathering a coalition of allies to bomb the Islamic State into oblivion as it seeks to destroy what’s been called “an existential threat” to this country. Congress has authorized the training and arming Syrian rebels, but hasn’t yet debated whether to send American aviators into hostile air space to bomb ISIL forces.

That’s warfare, as I understand the meaning of the term.

Shouldn’t we be having this debate? Shouldn’t Congress declare war on ISIL if that is what the commander in chief says is occurring as we seek to “degrade and ultimately destroy” this terrorist cult?
