Amy Davidson examines the Obama administration’s official justifications for continuing to conduct the war in Libya without congressional authorization, and finds them extremely weak tea.
That said, I’m having trouble getting worked up about this subject. The previous administration invaded and occupied Iraq without congressional authorization, and in fact every war the United States has started or involved itself in the past 60-plus years have been undeclared wars. World War II was the last time any POTUS chose to remember that only Congress has the power to declare war (a power already circumscribed by the War Powers Resolution of 1973).
Or, more succinctly, what Barbara O’Brien says.
